How the world celebrates Easter in 18 spectacular photos
From eggs to bunnies, there are almost as many ways to observe Easter as there are countries.
April 21 marks the Christian holiday of Easter this year, which summons thoughts of dyed eggs, elaborate parades, religious theater, and chocolate bunnies.

Today, Christians recognize Easter on the first Sunday after the first full moon of spring, but there wasn’t always a unified idea of when it should be. In the third century, Easter was determined by the Jewish holiday of Passover, observed two weeks after the first full moon of spring. Christians celebrated Easter shortly after Passover, but different regions celebrated it on different days.
