Every cloud retirement, with a countdown and a calendar

Retirement and end-of-support notices now have a home of their own on Cloud Releases: a list of every upcoming deadline, a countdown on each one, and a calendar you can subscribe to.
A countdown for every retirement
The new Deprecations page lists every retirement and end-of-support notice by the day it takes effect, soonest first, with the days left beside each one. Filter it by provider, and see the ones already in effect in their own tab.
Each deprecation's own page shows the countdown too, right under its title.

Deadlines that land in your calendar
Press Subscribe to calendar and add it to Google Calendar, Apple Calendar, Outlook, or any app that takes a calendar address. Every deadline shows up as an all-day event.
It is a subscription, not a one-off download: new deprecations and changed dates appear in your calendar by themselves.

Only the ones that affect you
If you follow services, the Following page now has a Deprecations tab, with its own calendar feed of just the deadlines for the services you run.
How the dates work
Providers rarely give the retirement date as data of its own, so Cloud Releases reads it from the announcement (“will be retired on March 31, 2027”). It finds a date for about 8 in 10 deprecations; the rest are listed under “No date given” so they don't get lost. If a date looks wrong, please tell us and we'll fix it.
Most of the list is from Microsoft Azure and Google Cloud for now: AWS rarely announces retirements in its “What's New” feed, which is where its updates come from.
