What I am looking for:
If current date is 1st january 2020, then i want 31st dec, 2020.
If its 1st feb 2020 then i want 31st jan, 2021.
Is there any way to get the above result without third party library?
What I tried was to add 365 days but as we know the days are not 365 always so it did not work.
Looking for solution
