understood the mistake
of the julian calendar year % 100 != 0 - superfluous
really don't understand why...

Hello my code passes tests with years > 1752
and where < 1752 are lost for several days (1, 3 ... somewhere around 10)
in tests, the rule of the julian calendar?
(year % 4 == 0) and (year % 100 != 0) ?
Or am I misunderstanding something, please tell me

print(f'Хах)) спасибо на добром слове)) И тебе всего хорошего + удачи ^^')

Wow, didnt expect to get an answer.
I even forgot)))
I solved this task with the "clumsy" method. Far from in not 30 minutes(((
Thank you very much, man. Very nicely explained
I'll add more from myself. Try to solve task on a piece of paper in the usual way, and then write this logic in the program code.

I'm sorry, very ... help explain the condition, please (((
what do they want from me?(((

And if it's not a secret, can you tell me more, please?
Сan i print the tests themselves or the behavior of my code on the tests?

you are just a genius, handsome, nanomachine, PROGRAMMER!!!
my brain flutters!!!

Thank you very much, I got the idea, I will try

Thanks...but what methods should I use?
Should obtain correct maximum subarray sum in 10 random tests with array size 10000 <= size <= 20000 and with integer entries -100 <= n <= 100

Testing are endless. No matter how you optimize the code, there are more and more checks

I'm certainly good... using 3 cycle for such a task...(sarcasm)

Sorry, but could you please point me in the right direction?

Hello, tell me, please, how can this be?

everything is green, everything works, but this...
