If 20 February 2013 was Wednesday, then what was the day of the week on 28 February 2016?

Sunday

Using Code Method :-

\(\frac{Date+Month code+Year code+Last 2 digits of yr+Leap yrs till given yr}{7}\)

( Note: Remainder of the above sum will be the code of week day }

20 Feb 2013;

20 + 04 + 06 + 13 + 03 = 46

remainder of \(\frac{46}{7}\) = 04

Therefore, the code of 04 is Wednesday

Similarly,

28 Feb 2016;

28 + 03 + 06 + 16 + 04 = 57

remainder of \(\frac{57}{7}\) = 01

Therefore, the code of 01 is Sunday
