As a religious nation, Greek Orthodox Easter is a week-long celebration that includes a series of festivities. The Holy Week, or Megali Evdomada, is brimming with symbolic events, festivities, and traditions followed by the whole nation, though the serious business begins around Holy (or Maundy) Thursday.
This day is when the Service of the Holy Passion takes place. Preparations for the Resurrection festivities start on that day.
It is traditionally on Holy Thursday that people make the Easter brioche, also known as tsoureki. This sweet bread is usually braided with three pieces of dough, which represent the Holy Trinity, and spiced with mahleb. It is served with a red hardboiled egg in the middle. Nowadays, people simply buy the tsoureki at the bakery as its preparation is time-consuming.
