What free calendar should we build next?

I've been building a free library of auto-updating calendar feeds 755 so far, around 38,000 events. Public holidays in 105 countries, league fixtures, anime and streaming releases, rocket launches, FOMC meetings, game release dates. Subscribe once in Apple Calendar, Google Calendar or Outlook and they keep themselves current nothing ever needs re-importing.

So: what schedule do you still check by hand because it lives on a website instead of in your calendar?

Name it and we'll put it on a list of feeds to be built.

Smart Calendar Feeds - 750+ free calendar feeds — or build your own with AI

750+ free calendar feeds — public holidays, sports fixtures, anime releases, rocket launches, earnings dates — that keep themselves up to date. Subscribe in one click in Apple, Google, or Outlook. No account needed. Don't see yours? Build one with AI from any prompt, PDF, spreadsheet or URL.

Smart Calendars AI 2.0 - An agentic calendar that schedules from anything you share.

SmartCalendars AI now adds an email-based + web-based AI assistant you can reach from anywhere. It stands out with agentic AI that can web-search to find real-world info (events, places, schedules) and turn it into structured calendar items and smart reminder. Along the way we added invite/attendee management, contact extraction from text, and Apple Watch voice capture—all in a fast, modern UI.
