If 30 January 2010 was Saturday, then what was the day of the week on 01 March 2011?

Tuesday

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 }

30 Jan 2010;

30 + 01 + 06 + 10 + 02 = 49

remainder of \(\frac{49}{7}\) = 0

Therefore, the code of 0 is Saturday

Similarly,

01 March 2011;

01 + 04 + 06 + 11 + 02 = 24

remainder of \(\frac{24}{7}\) = 03

Therefore, the code of 03 is Tuesday
