All Christians--East and West--are celebrating Holy Week and Easter at the same time this year! There are some differences, of course, as this Antiochian Orthodox website explains, including exactly when Lent ends:
Great Lent and Holy Week are two separate fasts, and two separate celebrations. Great Lent ends on Friday of the fifth week (the day before Lazarus Saturday). Holy Week begins immediately thereafter. Let's explore the meaning of each of the solemn days of Passion Week.
Lazarus Saturday: Lazarus Saturday is the day which begins Holy Week. It commemorates the raising of our Lord's friend Lazarus, who had been in the tomb four days. This act confirmed the universal resurrection from the dead that all of us will experience at our Lord's Second Coming. This miracle led many to faith, but it also led to the chief priest's and Pharisees' decision to kill Jesus (John 11:47-57).
Please read the rest there. Here is the schedule for services at St. George's Orthodox Christian Cathedral this week.
In honor of the occasion, I'm listening to Maximilian Steinberg's Passion Week!
