The main origin of the feast is the following: (See this video or read below)
Before the day of the feast, in the eveneing, we colour eggs. The original colour of the eggs is red which symbolizes the blood of Jesus Christ, however, nowadays other colours may also be used to make the table more colourful. Most of the people use a natural method that has been used hundreds of years before now-the red onion's cover. We take the cover of the red onion, add water and boil the eggs in that water. The darkest eggs on the photo above are coloured using this method.
The most interesting part of the Zatik for me is the "Egg fights". Each person chooses an egg and crash it to the others' eggs. This is like a competition, you should be able to keep your egg unbroken as long as possible.
Other famous meals for Zatik include "Chamichov Plav" (which is rice with raisins, rice symbolizes all the people and the raisins symbolize the people who believe in Jesus Christ), "Kanacheghen" (meals prepared from different types of greens). All these meals can be found in the video below.
On Sunday, the faithful welcome each other on the occasion of the Glorious Resurrection of Christ conveying the great tiding: "Khristos hariav i merelots" ("Christ is Risen from the dead") and receive the answer: "Orhnyal e harutyunn Qristosi" ("Blessed is the Resurrection of Christ").
The Armenian Church traditionally celebrates evening Divine Liturgy on the evening prior to Jesus Christ’s Glorious Resurrection (Easter). Following the conclusion of the Liturgy, the assembled faithful take lit candles home, symbolizing the Light that Christ brought into the world. The Divine Liturgy celebrated on the eve is the start of the festive ceremonies.
People also organize different celebrations, parties this day.
