Hi,
1 April 1970 is Wednesday.After each year,April 1 will be the next week
day.ie,1 April 1971 will be Thursday.But when the year is a leap year, it
will be the next week day.Hence 1 April 1972 will be Saturday(as in between,
February has 29 days) in a leap year.Based on this, there will be only 3
saturdays on 1 April 1972,1978 & 1989.A formula can be arrived ,but not so
easy.I have created a prpectual calendar & can get name of week on any date
after 1900(which year is not a leap year,even though 1900 is divisible by 4.
Thank you
