Rollout mini‑kit (paste‑ready) — mini widget + sticky CTA for state pages

Use this single bundle on Locations (state) and allergy‑season guides to deep‑link readers to the Start‑by calculator with their state auto‑selected.

1) Paste under the H1: Mini Start‑by widget

 var href=TOOL_URL+(state?('?state='+state):'')+'#startby-calculator';
 var a=document.getElementById('startby-mini-link'); if(a) a.href=href;
})();</script>

2) Add sticky CTA (bottom‑right)

<!-- Sticky "Check your start‑by date" CTA (bottom-right) -->

 var target=TOOL_URL+(state?('?state='+state):'')+'#startby-calculator';
 var l=document.getElementById('startby-link'); if(l) l.href=target;
})();</script>

3) Optional click tracking (recommended)

<script>(function(){
 function getState(u){var m=(u||'').match(/[?&]state=([A-Z]{2})/);return m?m[1]:''}
 function track(){try{var href=this.getAttribute('href')||'';var st=getState(href)||getState(location.search)||'';var placement=(this.id==='startby-mini-link')?'mini':'sticky';window.dataLayer=window.dataLayer||[];window.dataLayer.push({event:'startby_click',startby_placement:placement,startby_state:st,startby_href:href});}catch(e){}}
 var a=document.getElementById('startby-mini-link'); var b=document.getElementById('startby-link');
 if(a) a.addEventListener('click',track); if(b) b.addEventListener('click',track);
})();</script>

4) Add dateModified to each host page

<script type="application/ld+json">
{
 "@context": "https://schema.org",
 "@type": "WebPage",
 "name": "{{PAGE_TITLE}}",
 "url": "{{CANONICAL_URL}}",
 "dateModified": "{{YYYY-MM-DD}}"
}
</script>

QA checklist (5 minutes)Editor quick link helpers (for CMS that strips scripts)

• One-line link (grass): Add “Check your start-by date” pointing to https://www.wyndly.com/pages/grass-tablet-timing?state=XX#startby-calculator (replace XX with your state code; example: CA)

• One-line link (ragweed): Add “See ragweed tablet timing” pointing to https://www.wyndly.com/pages/grass-tablet-timing#ragweed-tablet-timing-2027

• Simple inline badge (no JS):

<p><a href="https://www.wyndly.com/pages/grass-tablet-timing?state=XX#startby-calculator" style="display:inline-block;background:#0b5cab;color:#fff;text-decoration:none;border-radius:999px;padding:6px 10px;font:600 14px/1.25 system-ui,-apple-system,Segoe UI,Roboto,Ubuntu,Arial,sans-serif;">Check your start‑by date</a></p>

• State deep-link pattern (replace XX): TOOL_URL?state=XX#startby-calculator. Examples: CA, OR, GA, OH, WI.

• Reminder: Also add dateModified JSON‑LD to each host page you touch (see template below in this guide).

• From a Locations page, click the widget and sticky CTA; confirm the tool opens with your state pre‑selected in the 2027 Quick finder.

• Test one extended‑season state (FL or TX) and one May/June peak state (WI or OH).

• Keep only one instance of the inline CSS/JS per page; ensure the CTA doesn’t overlap mobile UI; aria‑label stays intact.

Deep‑link pattern for editors

Paste‑ready: Pollen timing micro‑module (ZIP widget + sticky CTA)

Give editors a tiny, self‑contained pollen widget they can drop into state pages or season guides, plus a sticky CTA. It deep‑links to the Wyndly Pollen Index.

1) Mini pollen widget (inline, compact)

<!-- Mini Pollen widget (inline, compact) -->
<style>.pollen-mini{font:600 14px/1.25 system-ui,-apple-system,Segoe UI,Roboto,Ubuntu,Arial,sans-serif;background:#0b5cab;color:#fff;padding:10px 12px;border-radius:8px;display:flex;flex-wrap:wrap;gap:8px;align-items:center}.pollen-mini label{display:flex;align-items:center;gap:6px}.pollen-mini input{border-radius:999px;border:0;padding:6px 10px;min-width:110px}.pollen-mini a,.pollen-mini button{background:#fff;color:#0b5cab;border:0;border-radius:999px;padding:6px 12px;font-weight:700;cursor:pointer;text-decoration:none}.pollen-mini small{opacity:.9;font-weight:500}</style>
<div class="pollen-mini" aria-label="Check today’s pollen by ZIP">
 <span>Today’s pollen</span>
 <label for="pzip">ZIP:
 <input id="pzip" name="zip" pattern="\\d{5}" inputmode="numeric" placeholder="e.g., 19111" aria-label="Enter 5-digit ZIP" />
 </label>
 <button type="button" aria-label="See pollen for ZIP" onclick="(function(){var z=document.getElementById('pzip').value||'';var base='https://www.wyndly.com/pages/pollen-data-test';location.href=/^\d{5}$/.test(z)?(base+'?zip='+z):base;})();">See counts</button>
 <small>Source: Wyndly Pollen Index</small>
</div>

2) Sticky "See today’s pollen" CTA (bottom‑right)

 <span>See today’s pollen</span>
 <span class="pill">Wyndly Pollen Index</span>
 </a>
</div>

3) Optional click tracking (analytics‑agnostic)

<script>(function(){function getZip(u){var m=(u||'').match(/[?&]zip=(\d{5})/);return m?m[1]:''}function track(){try{var href=this.getAttribute('href')||'';window.dataLayer=window.dataLayer||[];window.dataLayer.push({event:'pollen_click',pollen_zip:getZip(href),pollen_href:href});}catch(e){}}var cta=document.querySelector('#pollen-cta a');if(cta) cta.addEventListener('click',track);})();</script>

How to cite this timing (copy‑block for editors)

<!-- Cite block: Pollen timing & dataset -->
<div style="font:600 14px/1.4 system-ui,-apple-system,Segoe UI,Roboto,Ubuntu,Arial,sans-serif;background:#eef2ff;border:1px solid #c7d2fe;color:#1e3a8a;padding:10px 12px;border-radius:8px;margin:10px 0;">

Start‑by quick links

Grass SLIT tablet timing by state — start at least 12 weeks before season (2027)

Quick start‑by finder (2027)

Select your state to see the on‑label “start by” dates and jump to your state guide.

Use this 2027 calendar to pick your on‑label “start by” dates for grass SLIT tablets (Grastek, Oralair). First tablet dose is supervised with ≥30‑minute observation; an epinephrine auto‑injector is prescribed for home use. Ages on‑label: 5–65 years.

Quick rules (unchanged for 2027)

• Grastek: start ≥12 weeks (84 days) before your local grass season begins.

• Oralair: start 4 months before your local grass season begins.

• Not sure about local timing? Check today’s pollen: See current counts

Start‑by calculator (inline) Choose your peak month and product to get your personal “start by” date.

Methods (how we generated 2027 dates)

• Labeled lead‑times from product information and society guidance: Grastek ≥12 weeks; Oralair 4 months; first dose supervised; epinephrine auto‑injector for home use (Wyndly safety overview).

• Peak grass month per Wyndly state guides (links below). Where guides list “May/June,” May is used to protect against early seasons.

• “Start by” dates are anchored to the 1st of the peak month (84 days or 4 calendar months prior). Local confirmation is recommended with the Wyndly pollen tracker and your clinician (pollen tracker).

• Context: climate variability can advance and lengthen pollen seasons (CDC overview).

How to cite this timing

Use these references when citing Wyndly’s grass tablet timing tool and dates:

• Lead-time rules and safety: Product labels and society guidance (first-dose supervision; Grastek ≥12 weeks; Oralair 4 months) — see notes above and Anaphylaxis & immunotherapy.

• Local confirmation: Wyndly Pollen Index dataset (daily, city-level). Access: Wyndly pollen tracker.

• Climate context: CDC overview.

• State assumptions and outputs: see 2027 calendar, Quick finder, and Extended-season states.

Suggested citation

Wyndly. Grass SLIT tablet timing by state: Grastek ≥12 weeks; Oralair 4 months. Methods and dates derived from product guidance, Wyndly state seasonality, and the Wyndly Pollen Index (daily). Accessed at https://www.wyndly.com/pages/grass-tablet-timing and https://www.wyndly.com/pages/pollen-data-test.

At‑a‑glance: Start‑by rules (on‑label tablets)

State‑by‑state “start by” calendar (2027)

Assumptions used for dates:

• “Peak grass month” = the month a state guide identifies grass as the dominant seasonal driver or notes summer grasses; where only “summer” is stated, June is used as a conservative default.

• “Start by (≥12 weeks)” = 84 days before the 1st day of the peak month (May → Feb 6, 2027; June → Mar 9, 2027).

• “Start by (4 months)” = 4 calendar months before the 1st day of the peak month (May → Jan 1, 2027; June → Feb 1, 2027).

• Always confirm locally with the Wyndly pollen tracker and your clinician.

Notes:

• Where a state page specifies “May/June,” use the earlier (“May”) to protect against early onsets in warm springs.

• For states not listed above, use your region’s typical peak (most U.S. regions peak in May or June for grasses) and back‑calculate with the rules above. Confirm against the pollen tracker.

Extended‑season states (year‑round or multi‑peak grass) — 2027 targeting

In climates with prolonged or multiple grass surges (e.g., Florida, much of Arizona, and parts of Texas), tablet therapy is usually targeted to the earliest spring grass peak in your area:

• If targeting an early March 2027 surge: Grastek start by December 1, 2026; Oralair start by November 1, 2026.

• If targeting an early April 2027 surge: Grastek start by January 1, 2027; Oralair start by December 1, 2026. Use the pollen tracker and your local Wyndly doctor to pin this down. FL • AZ • TX

Pet travel & dosing across time zones

Heading out with your cat or dog while you’re on SLIT tablets or drops? Keep your therapy on track with these tips:

• Keep your daily cadence: take your dose every day; don’t “make up” extra doses after missed days unless your Wyndly doctor instructs otherwise.

• Use a local-time anchor: pick a consistent local time at your destination (e.g., 8 AM local) so your dosing stays predictable as you cross time zones.

• Pack in your carry‑on: keep tablets or drop vials in your carry‑on with a copy of your prescription or plan summary; temperature swings and lost checked bags can disrupt therapy.

Safety notes (tablets): the very first Grastek/Oralair dose must be supervised in a healthcare setting with ≥30 minutes of observation, and you’ll be prescribed an epinephrine auto‑injector with training for home use. Learn more: Anaphylaxis & immunotherapy.

If your itinerary is complex or you miss multiple doses, message your Wyndly doctor for a quick plan to restart or adjust safely.> Updated for 2026: See your state’s “start by” dates below. We’ll try to pre‑select your state if you came from a Wyndly state guide. Jump to: 2026 dates • Quick finder

Linking tip for editors: use TOOL_URL?state=CA#startby-calculator (replace CA with the state code) for the strongest pre‑selected experience.

Rollout checklist for editors (Locations pages and grass articles)

Use this to deploy the mini Start‑by widget and sticky CTA across state guides and grass‑intent posts.

• Replace TOOL_URL_HERE with the canonical URL of this page (for example: https://www.wyndly.com/pages/grass-tablet-timing).

• Paste the Mini Start‑by widget at the very top of each Locations post and on grass‑intent Learning Center articles.

• Add the sticky "Check your start‑by date" CTA where allowed on those pages.

• Deep-link pattern: TOOL_URL?state=XX#startby-calculator (e.g., CA, OR, GA, OH). Prefer linking to the #startby-calculator anchor for fastest action.

• Verify preselection works:

• From a Locations page, click the widget/CTA and confirm the state auto‑selects in the Quick finder (query param) and persists via referrer if query is missing.

• Manually test at least two states, including one Extended season (e.g., FL or TX) and one May/June peak (e.g., WI or OH).

• Accessibility: keep the provided aria‑label on the CTA link; ensure link text remains visible.

• Performance: keep the provided inline CSS/JS as-is; do not duplicate multiple instances on the same page.

• QA in staging/mobile: ensure the CTA pill wraps on small screens and does not overlap site UI.

Placement guidance

• Locations guides: insert the mini widget directly under the H1; place the sticky CTA globally or just on grass‑relevant pages if needed.

• Grass‑intent articles (e.g., grass pollen, grass tablets): place the mini widget in the intro section and include the sticky CTA.Persistent inline link for grass‑intent postsStandard footer link for editors

• Add this to page footers or “Further reading” sections to standardize access to the timing tool.

• Default: Grass tablet start dates (state tool) → https://www.wyndly.com/pages/grass-tablet-timing

• State preselect (Locations pages): https://www.wyndly.com/pages/grass-tablet-timing?state=XX#startby-calculator (replace XX with the two‑letter code)

Copy‑ready HTML (footer)

<p><a href="https://www.wyndly.com/pages/grass-tablet-timing">Grass tablet start dates (state tool)</a></p>

• Add this one‑line link near the intro to standardize timing tool access: "Check your start‑by date" → https://www.wyndly.com/pages/grass-tablet-timing?state=CA#startby-calculator (replace CA with your state code). The ?state=XX query will pre‑select in the 2027 Quick finder and persist for 2026/2025.

• For non‑state articles (general grass content), omit the query or choose a representative state.

Editor note: Canonical tool URL

• Use https://www.wyndly.com/pages/grass-tablet-timing as the canonical destination in widgets and CTAs (replace TOOL_URL_HERE accordingly).

Use this 2026 calendar to pick your on‑label “start by” dates for grass SLIT tablets (Grastek, Oralair). First tablet dose is supervised with ≥30‑minute observation; an epinephrine auto‑injector is prescribed for home use. Ages on‑label: 5–65 years.

Quick rules (unchanged for 2026) Tip: On‑label lead times — Grastek: ≥12 weeks (84 days) before season; Oralair: 4 months before season. Not sure about local timing? Check today’s pollen: See current counts

Quick start‑by finder (2025)

Select your state to see 2025 “start by” dates and jump to your state guide.

• Grastek (timothy): start ≥12 weeks (84 days) before your local grass season begins.

• Oralair (5‑grass): start 4 months before your local grass season begins.

• If a state shows “May/June,” choose the earlier month to stay on‑label. Confirm locally with daily pollen data and your clinician.

Start‑by calculator (inline) Choose your peak month and product to get your personal “start by” date.

Methods (how we generated 2026 dates)

• Labeled lead‑times from product information and society guidance: Grastek ≥12 weeks; Oralair 4 months; first dose supervised; epinephrine auto‑injector for home use (Wyndly safety overview).

• Peak grass month per Wyndly state guides (links below). Where guides list “May/June,” May is used to protect against early seasons.

• “Start by” dates are anchored to the 1st of the peak month (84 days or 4 calendar months prior). Local confirmation is recommended with the Wyndly pollen tracker and your clinician (pollen tracker).

• Context: climate variability can advance and lengthen pollen seasons (CDC overview on allergens and pollen: https://www.cdc.gov/climate-health/php/effects/allergens-and-pollen.html).

At‑a‑glance: Start‑by rules (on‑label tablets)

State‑by‑state “start by” calendar (2026)

Assumptions used for dates:

• “Peak grass month” = the month a state guide identifies grass as the dominant seasonal driver (e.g., “June for grass”) or notes summer grasses; where only “summer” is stated, June is used as a conservative default.

• “Start by (≥12 weeks)” = 84 days before the 1st day of the peak month (May → Feb 6, 2026; June → Mar 9, 2026).

• “Start by (4 months)” = 4 calendar months before the 1st day of the peak month (May → Jan 1, 2026; June → Feb 1, 2026).

• Always confirm locally with the Wyndly pollen tracker and your clinician.

Notes:

• Where a state page specifies “May/June,” use the earlier (“May”) to protect against early onsets in warm springs.

• For states not listed above, use your region’s typical peak (most U.S. regions peak in May or June for grasses) and back‑calculate with the rules above. Confirm against the pollen tracker.

Extended‑season states (year‑round or multi‑peak grass)

In climates with prolonged or multiple grass surges (e.g., Florida, much of Arizona, and parts of Texas), tablet therapy is usually targeted to the earliest spring grass peak in your area:

• If targeting an early March 2026 surge: Grastek start by December 1, 2025; Oralair start by November 1, 2025.

• If targeting an early April 2026 surge: Grastek start by January 1, 2026; Oralair start by December 1, 2025. Use the pollen tracker and your local Wyndly doctor to pin this down. FL • AZ • TX

Introduction> On‑label safety notes (tablets): first dose must be supervised (≥30 minutes) in a healthcare setting, and an epinephrine auto‑injector is prescribed for home use; age range: 5–65 years for grass tablets (Grastek and Oralair). See FAQs below.> First‑dose supervised (tablets): Your very first Grastek or Oralair dose must be taken in a healthcare setting with ≥30 minutes of observation, and you’ll be prescribed an epinephrine auto‑injector for home use. Learn more in our immunotherapy safety primer: Anaphylaxis & immunotherapy.

FAQs: Starting grass SLIT tablets (Grastek, Oralair)

• When should I start?

• Grastek: start at least 12 weeks (84 days) before grass season in your area.

• Oralair: start 4 months before season. See your state’s timing in the calendar below and confirm locally with the pollen tracker.

• Do I need to take the first dose in‑office? Yes. The first tablet dose is supervised with ≥30 minutes of observation. After that, dosing is done daily at home with an epinephrine auto‑injector available. Read our safety overview: Anaphylaxis & immunotherapy.

• What ages are on‑label? Both Grastek and Oralair are labeled for ages 5–65 years.

• Tablets vs drops—what if I miss the “start‑by” window? Tablets are single‑allergen and must start before the season. If you miss the window or need multi‑allergen care, Wyndly’s SLIT drops can start any time and treat multiple triggers (SLIT vs shots • Are allergy drops safe?).

• How do I pick my state’s date? Use the state table below. If a state lists May/June, choose the earlier month to stay on‑label. Cross‑check daily counts with the pollen tracker.

• Where can I learn more about grass allergies? See our Grass pollen overview and state guides in the calendar (e.g., CA, OR, NC, OH, WI).

At‑a‑glance: Start‑by rules (on‑label tablets)

Notes:

• After the supervised first dose, continue daily dosing at home per your clinician’s instructions; keep your auto‑injector available and know how to use it (overview on immunotherapy safety).

• If you prefer multi‑allergen care or miss the tablet window, Wyndly SLIT drops can start any time and have a favorable safety profile (how safe are allergy drops?). Starting an FDA‑approved grass sublingual immunotherapy (SLIT) tablet early matters. For 2025, use this calendar to pick your “start by” date and stay on‑label for the product you use, then confirm locally with daily pollen data. If you prefer multi‑allergen care or miss your tablet window, Wyndly’s doctor‑guided allergy drops (SLIT) can start any time and are managed 100% from home.

Extended‑season states (year‑round or multi‑peak grass)

In climates with prolonged or multiple grass surges (e.g., Florida, much of Arizona, and parts of Texas), tablet therapy is usually targeted to the earliest spring grass peak in your area:

• If targeting an early March surge: Grastek start by December 1, 2024; Oralair start by November 1, 2024.

• If targeting an early April surge: Grastek start by January 1, 2025; Oralair start by December 1, 2024. Use the pollen tracker and your local Wyndly doctor to pin this down. FL • AZ • TX

Missed your window or have multiple allergies?

• Consider Wyndly SLIT drops. They’re physician‑prescribed, can include multiple allergens (grasses, trees, weeds, pets, dust mites), and can be started any month. Safety profile is favorable (rare severe reactions; no deaths reported from drops). Allergy drops vs. shots • Safety

• Not sure which path is best? Schedule a visit with a Wyndly physician for personalized timing and product guidance.

Key takeaways

• Start tablets early: Grastek ≥12 weeks; Oralair 4 months before grass season. First dose supervised; keep epinephrine at home.

• For most states peaking in May or June, “start by” dates are Feb 6 (12‑week) / Jan 1 (4‑month) for May peaks and Mar 9 (12‑week) / Feb 1 (4‑month) for June peaks.

• Extended‑season states should anchor to the earliest local spring surge and choose the earlier of the two “start by” dates.
