I am going to tell you one of the fastest method to find to day of any date from the year just by giving out 4 inputs. For this method you must know the code of the day and months.
These are the codes for the month:-
These are the codes for the days:-
Let's take an example:-
Find which day was
Let's start solving by giving the four inputs:-
--> Date =
--> Last 2 digits of the year =
--> Number of leap years occurred in that century = 67/4 =
Note that for this input JUST TAKE THE QUOTIENT NOT THE REMAINDER.
--> Code of the month =
By adding all the inputs we get the answer
Now, divide the result by 7 and ONLY TAKE THE REMAINDER.
= = 14 and the remainder is 4.
And 4 is the code which day you have to find.
And 4 is the code of
So, the answer is
