The term "Easter" refers to the Christian holiday that celebrates the resurrection of Jesus Christ from the dead, as described in the New Testament of the Bible. It is considered the most important and oldest festival of the Christian Church. Easter is typically celebrated on the Sunday following the first full moon after the vernal equinox, which can fall anywhere between March 22nd and April 25th.

Easter is celebrated in various ways around the world, but some common traditions include attending church services, participating in Easter egg hunts, decorating and exchanging Easter eggs, and enjoying festive meals with family and friends. Many Christians also observe a period of fasting and reflection called Lent in the weeks leading up to Easter.

In addition to its religious significance, Easter has also become associated with symbols such as the Easter bunny and Easter eggs, which are often used in secular celebrations. The Easter bunny is said to deliver eggs and other treats to children on Easter Sunday, while Easter eggs are often decorated and hidden for children to find.

Overall, Easter is a time of joy and celebration for Christians, marking the resurrection of Jesus and the promise of eternal life.
