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 Jan 2020; 01 + 0 + 6 + 20 + 05 = 32 remainder of \(\frac{32}{7}\) = 04 Therefore, the code of 04 is Wednesday
Similarly, 28 Feb 2021; 28 + 04 + 06 + 21 + 05 = 64 remainder of \(\frac{64}{7}\) = 01 Therefore, the code of 01 is Sunday |
