# Calan Gaeaf (31 Oct / 1 Nov): a short-notice seasonal hook for a Welsh farm-history brand
Harvested 2026-10-27 (skills harvest), 4 days before Nos Galan Gaeaf. Topic: riding a seasonal moment with real heritage content instead of generic Halloween posts.

## What the sources show (read unless marked)
- **The tradition is agricultural and Welsh.** Museum Wales (Amgueddfa Cymru) blog "Halloween Traditions" (read 27 Oct): Nos Calan Gaeaf, "the eve of the winter kalend", marked the end of the major farm tasks and the harvest and the end of the old Celtic year; a feast thanked neighbours for harvest help; Calan Gaeaf was associated with **slaughtering farm animals for winter**; spirits roamed, ghosts were seen "at midnight on every stile"; the *ladi wen* (white lady) and, mainly in North Wales, the *hwch ddu gwta* (tail-less black sow) linked to bonfires, with the chant "Adref, adref am y cynta', Hwch Ddu Gwta a gipio'r ola'". Wikipedia + BBC Bitesize (snippets): Calan Gaeaf = 1 Nov, the night before is an *Ysbrydnos* (spirit night).
- **The national museum uses it as an annual event.** St Fagans National Museum of History runs "Nosweithiau Calan Gaeaf / Halloween Nights", promoted bilingually Welsh-first on Facebook and an Instagram Reel (snippets, not opened). Welsh museums federation ran a "Nos Calan Gaeaf! Welsh Halloween!" activity day 30 Oct 2024 (snippet). The Welsh framing is the sector's own, not a stretch.
- **There is a ready folklore audience.** #FolkloreThursday interview with founders Dee Dee Chainey and Willow Winsham (Scrawl, 11 Oct 2018, read): started 2015, "well over 30,000 followers", the feed "often hits the limit of 2,400 tweets per day". It has since moved to Bluesky (FolkloreThursday Facebook page + Chainey's X bio "No longer here, find me on Bluesky", snippets). FAQ (snippet): they retweet actual folklore over creative work - so post the record, not a pastiche.

## How to do it (steps)
1. **Find the true local link** in our own material: harvest end, winter slaughter, stiles/field boundaries, a ghost or white-lady story tied to the parish, a dated farm record from late October/November. One real record beats five spooky graphics.
2. **One piece, three cuts**, ready by 30 Oct:
   - a short page/blog post (Welsh first, English beneath) with the record, its catalogue ID and the Museum Wales tradition as context;
   - a 2-3 slide carousel or quote card (record line + source line);
   - a 15-30 s captioned clip if a scene already exists (no new paid renders for this).
3. **Timing**: publish 30 Oct, social on the morning of 31 Oct, Bluesky #FolkloreThursday on **Thursday 29 Oct** (it's a Thursday day) with a genuine folklore item, and a 1 Nov "Calan Gaeaf, first day of winter" follow-up. Seasonal posts age fast; nothing after 2 Nov.
4. **Hashtags**: #CalanGaeaf #NosGalanGaeaf #FolkloreThursday, plus #Halloween once. Bilingual caption, Welsh first.
5. **The ask** is soft: "the full record is in the archive" -> internal link to the evidence page; the shop link only as first comment (Meta link limits, see facebook-group skill).
6. **Measure** against the channel's last 10 posts (reach, saves, link clicks); log one row in the experiment log. If it beats the median, add Calan Gaeaf, Calan Mai and Gŵyl Ddewi to the anniversary calendar.

## Pitfalls
- Generic pumpkins/witch clip-art reads as off-brand for an archive; use the farm and the record.
- Don't invent folklore for the farm. If no local story exists, say so and use the national tradition with the Museum Wales source.
- No new spend: reuse existing images/clips (render budget is at $0 today).

## How we apply it to Cedwyn
- Post: `/wales/blog/calan-gaeaf/` (or the blog theme's equivalent) built by the site/blog flywheel; quote card via the quote-pack format; Facebook (Great House Farm II) + Instagram @cedwynestate through the existing auto-social path at its own cadence (>=4 h apart, no duplicates) — this skill is a PROPOSAL for those runs, nothing posted from here.
- Public-text rules: never name the project lead; banned words (states, assertions, per, second-hand report, not checked, reported, deception, taken); no insignia; nothing about family holdings or addresses; no outbound links on Cedwyn (Museum Wales cited by name, not linked).
- Welsh-first matches the project lead's rule that Welsh was the default language before ~1970 (documentary brief).
- Cross-links: google-trends-seasonal-timing.md (when interest peaks), heritage-anniversary-hashtag-calendar.md (add the date), welsh-language-media-papur-bro-golwg360-heno.md (Welsh outlets if a local story turns up — press only on the project lead's GO).
