One of the biggest holidays is tomorrow - the Orthodox Easter.
It is literally the same with the Catholic Easter, in which I mean of course that the meaning behind it is literally the same - the difference is that the Orthodox Easter and always falls between April 4 and May 8 each year. This is because Orthodox believers' religious holidays are dictated by the Julian calendar, not the Gregorian (secular) calendar that most other modern civilizations use.
Furthermore, for the Orthodox Easter, it is a tradition to dye red eggs - with red symbolizing Jesus's blood.
Aaaaaaaand since I had spare time this week - I am all for showing my dyed red eggs!

Happy Easter to everyone celebrating it this week!
