So I'm on one project which was previously developed (I mean poorly developed) by another firm.

So this fucking guy who has done all the coding, I just fucking hate that guy because he has the shittiest logic and he doesn't know things should always be dynamic.

So he has written code(in PHP) where he has calculated the difference between DateTime and he is adding days, hours and minutes to another DateTime.

And it took me fucking 5hours to realize that he just forgot there is a thing called month which should be considered while doing this, I mean WHAT THE ACTUAL FUCK?

It was calculating like the difference between
2018-07-12 and 2018-09-18 are FUCKING 6 DAYS WTF!!!! SERIOUSLY? HOW COULD SOMEONE MISS THIS?WTF?!!!! FUCKING 5 HOURS FOR THIS?

Hush!! I think it is my bad that I thought it is DateTime issue and focused on that. I feel good now. Thanks.
