Bulgaria being a Christian Orthodox country celebrates Easter according to the Julian calender instead of the Gregorian calendar, used by many western countries.
At midnight on the Saturday before Easter Sunday, people gather at the church with red painted eggs and a bread, known as 'kozunak'. The priest proclaims three times 'Christ has risen' and the congregation replies 'Indeed he has risen'. After a special sequence of services, the clergy blesses the breads and eggs brought by the people.
