Good Friday is the Friday before Easter Sunday and it is a federal statutory holiday across Canada.
It's a complicated but precise formula that determines the day Easter Sunday is celebrated: It is the first Sunday after the first full moon in spring (after March 21st) which can occur as early March 22 and as late as April 25.
Good Friday marks the death of Jesus Christ according to the Christian religion. It is a fundamental part of Christianity along with the resurrection of Jesus on Easter Sunday.
Many agree that this is a more important holiday than Christmas since it is the ultimate proof that Jesus is the son of God because he came back from death.
