In the Western Christian calendar, Ash Wednesday is the first day of Lent and occurs forty days before Easter (excluding Sundays). It falls on a different date each year, because it is dependent on the date of Easter; it can occur as early as February 4 or as late as March 10.

During DST, clocks are turned forward an hour, effectively moving an hour of daylight from the morning to the evening.

Interesting way to remember this: "Spring forward, Fall back"
