Surry Hills, Holy Trinity Greek Orthodox Church

The Holy Trinity Greek Orthodox Church in Surry Hills was the first Greek Orthodox church in Australia, consecrated in 1898. This week is Holy Week leading up to Easter, for Eastern Orthodox denominations. The reason for the variation is complicated and goes back to the 4th century when the Church of Rome decided that the date of Easter would be computed independently of any Jewish calculations to determine the date of Passover, so that Easter is observed on the Sunday after the first full moon on or after the day of the vernal equinox. The Eastern Orthodox Churches continue to use a lunisolar cycle to calculate the date of Easter, which is also used to calculate the date of Jewish Passover.
