The next upcoming Easter Monday is on Monday April 1st, 2024.
Many countries will celebrate the day with egg rolls and dousing water (holy water that was blessed on Easter Sunday) on one another. Most countries take the day off as a day for rest and time to spend with family and friends. Many depending on their latitude to the earths equator can enjoy the early spring weather with its warner days.
Historically this day was considered bad luck and called Black Monday possibly because it marked the end of the Easter break for school children.
