While the terms are often used interchangeably, Easter and the resurrection of Jesus are related but not precisely the same thing.
* Resurrection of Jesus: This refers to the event of Jesus Christ rising from the dead, three days after his crucifixion. It's the central event in Christianity and the foundation of Christian faith.
* Easter: This is the Christian holiday that celebrates the resurrection of Jesus. It encompasses the period around the resurrection, including Good Friday (the day of Jesus's crucifixion) and Easter Sunday (the day of his resurrection). Easter involves traditions, customs, and religious observances related to the resurrection.
So, the resurrection is the specific event, while Easter is the holiday that commemorates and celebrates that event.
