PS you can add support for 3.14 and drop EOL 3.8 and 3.9 :)

Awesome, thanks @hugovk! Also for the typo-fix 😆

Will do, thanks for reminding!

May I ask a related question: do you know if future EOL dates of Python versions, e.g. 3.10, 3.11, will always go EOL on the end of October? Because I noticed that for non-yet EOLed version, the end_of_life has no day specified yet, for example 3.10 -> 2026-10.
But already EOLed versions have a day (obviously), like for 3.9 it is 2025-10-31 and for 3.8 it is 2024-10-07 (not end of month).

I just ask because I am unsure whether I should use the end or start (or even the middle?) of the future EOL month to calculate the days until EOL.
