Easter Sunday is the day when Christians celebrate Christ’s return to life and victory over the death. On this day many people go to church. Children get presents of chocolate Easter eggs. Easter always means spring, new life after winter, flowers, green trees and young animals, especially lambs and chicks. Some time ago it was a tradition to make new clothes and hats for Easter.
Celebrating Hallowing is a very old tradition. Long ago people thought that on 31 October spirits of the death came back. That’s why now some people dress up as witches and ghosts. They make lamps of pumpkins. Sometimes children go out in groups, knock on peoples doors and say “Trick or treat”. They usually get a treat, some sweets or nuts. People also have Halloween parties where they often play games.
Guy Fawkes’ Night is on 5 November. That day in 1605 some conspirators wanted to blow up the Houses of Parliament and kill King James I and his ministers. Guy Fawkes was one of them. But they couldn’t do that because the king’s men caught Guy Fawkes and killed him. Not many people think about those events now but they enjoy celebrating the day with their friends and families. On 5 November when it gets dark, people go out into the streets and watch beautiful fireworks. In the country they often make big bonfires and gather near them.
