The Christian calendar is full of pitfalls. But if you assume that Jesus was crucified in 33 or perhaps 29, then the Christian world is heading straight towards an important anniversary: 2000 years of Easter is almost around the corner. Reason enough to think a little about what exactly is celebrated with this festival, which is theologically even more important than Christmas. The core of the process is usually still somewhat familiar to people who are unfamiliar with the church: On Good Friday, the death of Jesus on the cross is remembered, Saturday was long considered “the quietest day of the year” (which Jesus spent in his death’s sleep), and on the Easter night it is announced what is supposed to bring bright joy on Sunday – the grave is empty, the first Christians saw their prophet as a risen man.
