As this is Holy Week, I am doing a series of links to articles on the Miracle of the Holy Fire, which occurs at the same place, the Church of the Holy Sepulchre in Jerusalem on Holy Saturday.
The miracle occurs every year on the Orthodox Easter Saturday. There are many types of Orthodox Christians: Syrian, Armenian, Russian and Greek Orthodox as well as Copts. In the Holy Sepulchre Church alone there are 7 different Christian Denominations. The Orthodox Easter-date is fixed according to the Julian Calendar, and not the usual Western European Gregorian calendar, which means that their Easter normally falls on a different date than the Protestant and Catholic Easter.
