If 01 March 2012 was Thursday, then what was the day of the week on 01 February 2016?

Monday

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 }

01 March 2012;

01 + 04 + 06 + 12 + 03 = 26

remainder of \(\frac{26}{7}\) = 05

Therefore, the code of 05 is Thursday

Similarly,

01 Feb 2016;

01 + 03 + 06 + 16 + 04 = 30

remainder of \(\frac{30}{7}\) = 02

Therefore, the code of 02 is Monday
