There is no avoiding a four-day Easter weekend. Easter Sunday falls relatively late on April 17, This gives us Good Friday on April 15 and Easter Monday on April 18. While it is not a holiday, the related Masopust, also called Mardi Gras or Carnevale, falls on Tuesday, March 1. The following day is Ash Wednesday, the start of Lent, the season of austerity leading up to Easter for devout Christians.
