How often does it happen that a holy day clashes with a hellish day? It happened only three days ago, when a calendaric (is there even such a word?) date occurs to combine Easter Sunday with April Fool’s Day.

That’s an opportunity for churchgoers to take part in both events.

Easter Sunday is one of those holy days that flit all around the calendar; sometimes it falls in March, sometimes in April. My birthday is constant, on April 21, but Easter is not. However, I can recall several times when my birthday fell exactly on Easter.
