How we now celebrate the calendar is not in fact how it came to be, though the length of each season actually gives a good indication of their importance and the order in which they developed in the church.

The shocking and unexpected resurrection of Jesus is the defining moment in the Christian calendar.  It is from this point that the Christian way of marking time began.
