In our calendar system, every 7 days later, the DAY repeats. For example: If 11th Jan is Friday (assume), then 25th Jan is also Friday since the gap is 14 days, i.e. 2 weeks; and hence, the day repeats. To find the day, we should divide the number of days by 7 and find the remainder; then add this remainder to the given day.
For example, if 11th Jan is Friday, for 30th Jan we have: Number of days = 19; remainder when 19 is divided by 7 is 5
=> Required day is 5 days after Friday, i.e. Wednesday
From February 28, 1999 (Sunday) to February 27, 2000 => This constitutes a NON-LEAP year i.e. there are 365 days
Thus, in our case, we have: Gap is 365 days => remainder when 365 is divided by 7 is 1
=> 28th Feb 2000 is 1 day after Sunday i.e. Monday
