A common year is 365 days, one day more than 52 weeks. So March 31 moves on one weekday each year: Tuesday in 2026, Wednesday in 2027. The jump is two days when February 29 comes in between, so March 31, 2028 is a Friday, two on from 2027's Wednesday. Between 1901 and 2099, the whole pattern repeats every 28 years.
