What is a public ICS calendar feed?
An ICS file (iCalendar format) is the universal calendar standard. Any app that supports webcal — Google Calendar, Apple Calendar, Outlook, iPhone, Android — can subscribe to an ICS feed. Events sync automatically whenever the source updates.
The most complete free collection
Public ICS feeds are scattered across hundreds of websites with no central place to find them. This is the most complete directory of free calendar subscriptions anywhere — every feed hand-picked and organized by category, so you find a working iCal link in seconds instead of hunting the web.
Works everywhere — even on e-ink
Every feed here is a standard ICS subscription that works in Google Calendar, Apple Calendar and Outlook. Prefer an always-on display? Add any calendar to a PaperSync e-ink calendar in one tap and see your schedule at a glance.
Which calendar apps support ICS subscriptions?
Google Calendar, Apple Calendar (Mac and iOS), Microsoft Outlook (desktop and web), Thunderbird, Samsung Calendar, and virtually any app that supports the webcal:// protocol or icalendar imports.
How do I subscribe to a public ICS calendar?
Copy the ICS URL from any feed's detail page, open your calendar app, and paste it as a new calendar subscription. The process takes under a minute. See our step-by-step guide for every major app.
