HolidayOps

Every working day, in every country. HolidayOps merges public holidays, each country's own weekend and your company's closures into one answer, for 250 countries and 624 regions. It is a REST API, a web app, private iCal feeds, monthly email digests and signed webhooks, in English, Urdu and Arabic, built on the open-source holidays library.

Status: feature-complete across all milestones. Hosting is planned for launch; until then HolidayOps runs locally or on your own server. See docs/status.md.

The source of truth

This wiki is a short guide. The detailed, reviewed documentation lives in the repository and is updated in the same pull request as the code:

  • README: features, setup, keys, troubleshooting
  • docs/: architecture, security, SEO, deployment, design notes per milestone
  • CHANGELOG: what changed, newest first
  • SECURITY.md: how to report a vulnerability

If the wiki and the repository disagree, the repository is right. Please open an issue so the wiki gets fixed.
