How to subscribe
- Tap your calendar button above — Apple and Outlook desktop open the webcal link directly.
- Google and Outlook.com open in a new tab — confirm “Add calendar” there.
- New events appear automatically; you never re-subscribe.
On iOS, webcal links open Calendar's subscription sheet. If nothing happens, copy the feed URL above and add it via Settings > Calendar > Accounts > Add Subscribed Calendar.

How it works
Subscribing is not a one-time import: your calendar app keeps the feed connected and refreshes it periodically (roughly every 12 hours), so newly announced crypto show up on their own. Each entry links back to its live countdown page.
