Support deadlines, verified at the source.
A free library of end-of-support dates for .NET, PHP, Windows Server and SQL Server, with guides and free data files. We maintain it ourselves: every date is checked against the vendor’s own lifecycle page and cross-checked with endoflife.date, and shows the day it was verified.

How it’s built
Verified at the source, dated, and corrected in the open. The full method is one page.
- 01
Primary sources
Every date comes from the vendor’s own lifecycle page: Microsoft Learn and the .NET support policy, and php.net.
- 02
Cross-checked
Each date is compared with endoflife.date. Where they disagree, the vendor’s page decides and we check again.
- 03
Dated
Every row shows the day it was last verified. We aim to re-check every row each week, and always in the week before a deadline; a date only moves when its source does.
- 04
Corrected in the open
Changes and corrections are logged with their date. Anyone can report a problem, no account needed.
