Daymark

Daymark is the product site and Apple Calendar subscription service for Chinese holiday, solar-term, and adjusted workday reminders.

• packages/calendar exposes @daymark/calendar, the shared iCalendar generator.
• apps/docs/index.html is the public product homepage source.
• apps/docs/scripts/build.mjs renders that HTML and a preview .ics file into apps/docs/dist.
• apps/worker serves the live .ics subscription endpoint.
• Event UID values are stable across releases to avoid duplicate events.
• Calendar responses include content type, validators, and cache headers.

The source repo stays private. The public product surface is:

https://daymark.agentclub.dev/
https://daymark.agentclub.dev/calendar/daymark.ics

pnpm install
pnpm test
pnpm build

Generated artifacts are written under each app, for example apps/docs/dist.

Daymark is provided at:

https://daymark.agentclub.dev/
https://daymark.agentclub.dev/calendar/daymark.ics

The homepage presents Daymark as a product page for Chinese holiday, solar-term, and adjusted workday subscriptions. It includes one-click copying for the live subscription URL:

https://daymark.agentclub.dev/calendar/daymark.ics

The live calendar endpoint uses two protections:

• Edge caching for the .ics response. Repeated requests can be served from cache, and conditional requests with a matching ETag return 304.
• Rate limiting with CALENDAR_RATE_LIMITER, configured at 60 requests per 10 seconds per cf-connecting-ip.

The production WAF rule targets the public subscription path:

Expression:
(http.host eq "daymark.agentclub.dev" and http.request.uri.path eq "/calendar/daymark.ics")

Suggested action:
Managed Challenge or Block

Suggested threshold:
60 requests per 10 seconds per IP

Daymark prefers reviewed local holiday schedules when available. For future years that are not yet maintained locally, the service can supplement adjusted holiday data from the timor.tech holiday API at https://timor.tech/api/holiday/year.

This version covers deterministic festival reminders, solar terms, and reviewed adjusted holiday schedules. Future public holiday schedules can be added locally or fetched by the service when the official year data is available.
