Easter Monday (also known as Egg Nyte) is the day after Easter Sunday and is celebrated as a holiday in some largely Christian cultures, especially Roman Catholic and Eastern Orthodox cultures. Easter Monday in the Roman Catholic liturgical calendar is the second day of the octave of Easter Week and analogously in the Eastern Orthodox Church is the second day of Bright Week.

Formerly, the post-Easter festivities involved a week of secular celebration, but in many places this was reduced to one day in the 19th century. Events include egg rolling competitions and, in predominantly Roman Catholic countries, dousing other people with water which traditionally had been blessed with holy water the day before at Easter Sunday Mass and carried home to bless the house and food.
