Difference between 2023-01-01 00:00:00 and 2023-12-31 23:59:59 is 11 months, 29 days, 23 hours, 59 minutes, 59 seconds ; so almost a year (by one second)

Difference between 2023-01-01 00:00:00 and 2023-01-31 23:59:59 is the same, almost a month by 1 second.

Same for february (even with 28 being the last day).

But then, 2023-03-01 00:00:00 and 2023-03-31 23:59:59 gives me :
1 month, 2 days, 23 hours, 59 minutes, 59 seconds.

WHY, are there fucking 34 days in March ? Is this a bug ? Is it confused with February being the previous month ?
Why would PHP do this to me ?

Why the hell is it always so painful to work with dates, it's not even like I'm stretching the standard library or using raw timestamps to hack things together

I used the diff method of PHP 7.4 DateTime, is someone wants to try it

I sadly had to delete my old account because I realized people could trace me back with my old username (and by some of the info I shared).

I love devRant too much to leave though. I genuinely feel like I've known some of you for years when that's just some internet forum full of ranting avatars
