Always check that the given year is Leap Year or normal Year. If Leap Year and February encluded then the extra/ odd day of that Feb. month will be 1.If Normal Year and February encluded then the extra/ odd day of that Feb. month will be 0. ( As per table no-II). Here, the day will be count after the given date(1 January). So after 1 January, we get 30 days for January month and complete Feb., Mar., and April up to 5 days.
The extra day of Jan =2 (If 30÷7, the remainder will be 2)
The extra day of Feb.=1(2024 is Leap Year and so Feb’s extra day is 1) ☆ SeeTable-II
The extra day of Mar =3
The extra day of April =5 (April month has only 5 days so the extra day is 5, less than 7)
Total extra days=11 ( Which is greater than 7, so again must divide by 7 to get a total extra day)
Therefore, 11÷7 provide the remainder 4. Hence 4will be the final extra day of whole period)
