While Easter Sunday tends to fall in early to mid April, and occasionally at the end of March, it has only fallen precisely on April 1(Also known as April Fools Day) a few times. 2018 is the first time in 73 years that the calendar coincidence has occurred. Easter Sunday changes every year, depending on the March equinox (where scientists use a math calculation for the dates of the sun passing the equator). Ash Wednesday is determined by Easter’s date, so Ash Wednesday and Valentines’ Day fall on the same day as do Easter and April Fools Day.

The Sunday on which Easter falls was set back in 325AD by the Council of Nicaea, which ordered that the holiday would always fall on the first Sunday after the first full moon occurring on or after the equinox. With years of tradition, people will now be celebrating Ash Wednesday and Valentines’ Day on Feb. 14 and Easter Sunday and April Fools Day on April 1.
