Easter, also known as Resurrection Sunday, is a Christian holiday that celebrates the resurrection of Jesus Christ from the dead. It is observed on the first Sunday after the first full moon following the vernal equinox, typically between March 22 and April 25.

The origins of Easter can be traced back to the Jewish holiday of Passover, which commemorates the Israelites' liberation from slavery in ancient Egypt. According to the New Testament, Jesus celebrated Passover with his disciples on the night before he was crucified. He then rose from the dead three days later, on what is now known as Easter Sunday.

Easter has been celebrated by Christians for over 2,000 years and is one of the most important holidays in the Christian calendar. It is a time of joy and celebration, as it represents the triumph of life over death and the promise of eternal life for those who believe in Jesus Christ. Many Christians attend church services and participate in special traditions, such as lighting candles, singing hymns, and exchanging Easter eggs and other gifts.

In addition to its religious significance, Easter has also become a secular holiday celebrated by many cultures around the world. In the United States, for example, it is often associated with the Easter Bunny and egg hunts. Regardless of how it is celebrated, Easter remains a significant holiday that brings together communities and reminds us of the power of faith and hope.
