Easter is a Christian holiday that celebrates the resurrection of Jesus Christ from the dead. The holiday is observed on the first Sunday following the first full moon after the vernal equinox, which usually falls between March 22 and April 25. Easter is preceded a period of fasting and repentance known as Lent, and culminates in Holy Week, which includes Palm Sunday, Maundy Thursday, Good Friday, and Holy Saturday. It is a time of joy and celebration for Christians around the world, who greet each other with the phrase “Christ is risen!”
