In the UK,schools close for about two weeks at Easter *** on to find out more about how Easter is celebrated in *** does it mean?Easter is a spring festival of new life. As a pagan tradition, it is the beginning of growth and new life after the cold, winter months. The name comes from the Anglo-Saxon goddess of the dawn and spring—Eostre. For Christians, Easter celebrates the resurrection of Jesus Christ. Easter celebrates life and rebirth, which is why we see lots of symbols of new life and fertility at Easter, like eggs, chicks and rabbits.
