If 13 September 2003 is a Saturday, then what will be the day of the week on 14 February 2005? |
Friday Wednesday Monday Saturday |

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 } 13 Sep 2003; 13 + 06 + 06 + 03 + 0 = 28 remainder of \(\frac{28}{7}\) = 0 Therefore, the code of 0 is Saturday
Similarly, 14 Feb 2005; 14 + 04 + 06 + 05 + 01 = 30 remainder of \(\frac{30}{7}\) = 02 Therefore, the code of 02 is Monday |
