If 2 March 2022 was a Wednesday, what day of the week was it on 2 March 2006?

Thursday

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 }

02 March 2022;

02 + 04 + 06 + 22 + 05 = 39

remainder of \(\frac{39}{7}\) = 04

Therefore, the code of 04 is Wednesday

Similarly,

02 March 2006;

02 + 04 + 06 + 06 + 01 = 19

remainder of \(\frac{19}{7}\) = 05

Therefore, the code of 05 is Thursday
