A 2027 content calendar should reserve most of its capacity for evergreen pages and refreshes, and use festival and seasonal moments as a planned overlay with lead times of at least six to eight weeks. Fund fewer, better pages, name an owner for measurement, and leave a quarter of the year unplanned for news. This post gives the structure, the key 2027 India dates with their uncertainties, and a template, as of 14 October 2026.
Key Takeaways
- Plan in four buckets: evergreen new pages, refreshes, seasonal and festival pages, and a reserve for news.
- Festival pages should be built and published well before the date, then updated each year rather than re-created.
- Google says pages must be indexed and eligible to show with a snippet to appear in AI Overviews and AI Mode, and no special files or markup are needed, so the calendar should fund fundamentals, not tricks.
- Festival dates in the Hindu calendar depend on location and source. Verify before you commit dates in a campaign brief.
- Quotas for volume are risky. Google's spam policies describe scaled content abuse; refreshes and quality beat output counts.
Start from what you already have
A calendar that starts with a blank sheet duplicates existing pages. StoryChief's calendar guide starts with an automated content audit to find decaying content, ranking drops, outdated facts, missing internal links and competitor gaps, and ends with monitoring to inform the next cycle (StoryChief). That is a vendor workflow, but the order is sensible: audit, then plan.
Run the audit with the method in my year-end content audit. Output: a list of pages to keep, refresh, merge or retire, and a list of gaps.
The four-bucket model
| Bucket | Share of capacity (my starting point) | What goes in it |
|---|---|---|
| Evergreen new | 30-35% | Pages answering recurring buyer questions, comparisons, pricing and process |
| Refresh | 30-35% | Updates to pages that already earn impressions or citations |
| Seasonal and festival | 15-20% | Dated campaigns, festive landing pages, exam and admission seasons |
| Reserve | 15-20% | Algorithm news, product launches, opportunistic topics |
These shares are my planning defaults, not research findings. Adjust to your business. The principle is the point: the reserve exists so you can react without cannibalising planned work.
The HOTH's 2027 planning brief, a vendor piece, argues that budgets are flat and that anything funded for AI search has to be paid for by something you stop funding, and recommends refreshing existing pages over publishing quotas (The HOTH). Its figures are cited from Gartner and a Stacker and Scrunch study at second hand, so check originals before quoting them. The planning logic still applies: decide what you will stop doing.
What the calendar should not fund
Google's AI features documentation states there are no additional requirements to appear in AI Overviews or AI Mode, that no new machine-readable files, AI text files or markup are needed, and that no special schema is required (Google Search Central). So do not put "llms.txt rollout" or "AI schema project" on the calendar as growth bets. Put technical health on it: indexing, snippet eligibility, site speed, broken links.
Also guard against volume for its own sake. Google's spam policies describe scaled content abuse as many pages generated mainly to manipulate rankings, including AI-generated pages that add no value (Google spam policies).
Quarterly structure
Q1 (January to March): foundations and refresh
- Audit and consolidate. Fix indexing and cannibalisation.
- Refresh the top 20 pages by impressions or citations.
- Build the year's evergreen hubs.
- Festivals: Makar Sankranti and Pongal (mid-January), Republic Day (26 January), Holi (around 22 March), Eid al-Fitr (around 10 March, provisional).
Q2 (April to June): conversion and admissions content
- For edtech and course brands, admissions and exam-result seasons often drive questions on fees, eligibility and comparisons. Build the money pages early. See my edtech fee page approach for page structure.
- Festivals: Ram Navami (around 15 April), Chaitra Navratri start (around 7 April).
Q3 (July to September): the long festive runway
- Raksha Bandhan, Independence Day, Janmashtami, Ganesh Chaturthi, Onam fall between mid-August and mid-September.
- Start festive landing pages in June or July, not the week before.
Q4 (October to December): peak season and review
- Navratri, Dussehra and Diwali dominate October. Year-end content is for audits and planning.
- Publish the review and the next year's plan by December.
2027 India dates, with caveats
Hindu festival dates vary by regional calendar and by the location used to calculate them. I checked two sources and they differ in places.
| Festival | Calendarific (India list) | Drik Panchang (page shows a US location) |
|---|---|---|
| Makar Sankranti | not listed in my read | 14 Jan 2027 |
| Pongal | 15 Jan 2027 | not checked |
| Republic Day | 26 Jan 2027 | not applicable |
| Eid al-Fitr | 10 Mar 2027 (provisional) | not checked |
| Holi | 22 Mar 2027 | 22 Mar 2027 (Holika Dahan 21 Mar) |
| Ram Navami | 15 Apr 2027 | not checked |
| Independence Day | 15 Aug 2027 | not applicable |
| Raksha Bandhan | 17 Aug 2027 | 16 Aug 2027 |
| Janmashtami | 25 Aug 2027 | 24 Aug (Smarta) or 25 Aug (ISKCON) |
| Ganesh Chaturthi | 4 Sep 2027 | 3 Sep 2027 |
| Onam | 12 Sep 2027 | not checked |
| Sharad Navratri begins | 30 Sep 2027 | 30 Sep 2027 |
| Dussehra | 9 Oct 2027 | 9 Oct 2027 |
| Diwali | 29 Oct 2027 | 28 Oct 2027 (Lakshmi Puja) |
| Christmas | 25 Dec 2027 | not applicable |
Sources: Calendarific, India 2027 and Drik Panchang, 2027 Hindu calendar. Drik Panchang's page notes dates depend on location and showed a California location when I read it, so day-level differences are expected. Before you finalise any campaign date, confirm with an India-based panchang source for your target city, and treat Eid dates as dependent on moon sighting.

Lead times: work backwards
Festive and seasonal pages need time to be crawled, indexed and updated. I use these defaults:
- Eight weeks before: brief approved, page URL fixed. Reuse last year's URL if one exists.
- Six weeks before: draft live, indexed, internal links in place.
- Four weeks before: first update with current offers or facts.
- Event week: monitor, fix, add live details.
- One week after: archive details but keep the page, mark as updated.
These are my working defaults, not Google guidance. Indexing is not guaranteed on any timetable; Google says sitemaps and links help discovery but do not guarantee it (Google Search Central, sitemaps).
Keep URLs evergreen
Create one URL per recurring event, such as /diwali-offers, and update it every year rather than creating /diwali-offers-2027 and /diwali-offers-2028. The old page already has links and history. When you update, change the visible date and facts, and make the lastmod in your sitemap reflect real changes. Mueller's comments on sitemaps, as summarised by Relevant Audience, say Google uses lastmod only when dates look reasonable and that it should reflect major changes (Relevant Audience). That is a secondary source, so confirm in Google's documentation if you rely on specifics.
Plan for AI answers, not only rankings
Add three recurring tasks to every month:
- Run your prompt panel and log which sources appear and what is wrong. My method is the 50-prompt panel.
- Check Search Console. Previsible reports Google announced generative AI performance reports on 3 June 2026 for a subset of sites first, so see whether your property has them (Previsible).
- Fix facts that assistants get wrong, starting with pricing, dates and eligibility.

The calendar template
Use one row per content item.
| Field | Notes |
|---|---|
| Item | Working title |
| Bucket | Evergreen, refresh, seasonal, reserve |
| Target question | The buyer question it answers |
| URL | Existing or planned |
| Owner | Writer and approver |
| Brief due / Draft due / Live by | Backward from the date |
| Event date | With source and confidence |
| Primary metric | Impressions, citations, signups |
| Review date | When you judge it |
Add a column for "what we stop doing" at the quarterly level. It forces trade-offs.
Quarterly review ritual
At the end of each quarter:
- Compare plan with output. Which items slipped and why?
- Look at performance by bucket, not just by page.
- Move unspent reserve into refreshes.
- Re-confirm festival dates for the next quarter.
- Update the calendar and write down what changed.
Google's helpful content guidance asks you to consider who the content is for and why it exists. A calendar entry that cannot answer "why would a person want this" should be cut (Google Search Central). Follow that with my Q4 2026 content plan for a near-term example of the same logic.
FAQ
What should a 2027 content calendar include?
Four buckets: evergreen new pages, refreshes, seasonal and festival content, and a reserve for news. Add owners, lead times and review dates.
When should I start festival content?
Roughly six to eight weeks before the event for the first live version, then update. This is my working default, not a Google rule.
Are 2027 festival dates fixed?
Gregorian-calendar dates like Republic Day are. Hindu festival dates depend on regional calendars and location, and Eid depends on moon sighting. The sources I checked differ by a day for several festivals, so confirm for your city.
Should I create new pages for each year's festival?
Usually no. Keep one URL per recurring event and update it annually to retain links and history.
How much should I publish in 2027?
There is no correct number. Google's guidance warns against content created mainly to attract search visits, and its spam policy covers scaled content abuse. Prioritise pages that serve a clear need.
Do I need special content for AI Overviews?
Google says no additional requirements apply beyond being indexed and snippet-eligible, and no special markup is needed. Focus on useful, accurate pages.
What goes in the reserve?
Time for algorithm updates, product launches, competitor moves and questions that appear in sales calls. I suggest 15 to 20% of capacity, adjusted to your business.
How do I fit refreshes into the plan?
Treat them as first-class items with owners and dates. Pick pages by impressions, citations or decay, and update facts, examples and internal links.
Which tools do I need?
A spreadsheet or board is enough. Content platforms can help, but the discipline is in audits, ownership and review.
How often should I revisit the calendar?
Quarterly for a formal review, monthly for a quick check on festival lead times and news reserve use.
