Easter is the most important festival in the Christian calendar. It celebrates Jesus rising from the dead, three days after he was executed.
The week leading up to Easter is called Holy Week.
Palm Sunday: this is the Sunday before Easter Sunday.
It is the first day of Holy Week and celebrates Jesus's arrival in Jerusalem riding on a donkey. Crowds of people came out of the city to greet him, throwing down palm branches on the road.
Anglican and Roman Catholic churches give out small crosses made from palm leaves, as a reminder of Jesus's entrance into Jerusalem and his death on the cross. Some Christians keep these in their homes all year as a symbol of their faith.
Maundy Thursday: this is the Thursday before Easter Day.
On Maundy Thursday Christians remember when Jesus ate the Passover meal with his disciples, breaking bread and drinking wine. Christians refer to this meal as the Last Supper.
Many Christians remember the Last Supper by sharing bread and wine together in a church service called Holy Communion, Eucharist or Mass. It is a reminder that Jesus sacrificed his life for mankind.
Good Friday is the Friday before Easter Sunday.
It commemorates the execution of Jesus by crucifixion.
Good Friday is a day of mourning in church. During special Good Friday services Christians remember Jesus's suffering and death on the cross, and what this means for their faith.
