For Christians, @drhakam, Easter is the most important day of the year. It was originally called Resurrection Sunday, as it is a celebration of the resurrection from the dead, of Jesus Christ. This occurred on a Sunday, following his execution by death on a cross on the preceding Friday.
Please feel free to ask any questions. If I can answer them, I will be happy to do it.
What is the significance to a Muslim, of the Eid celebration you mentioned?
