That matters for a countdown because a rule can be evaluated for any year, this one or one twenty years out, without waiting for an announcement. Every date on this page comes out of that rule rather than out of a list someone typed in, so nothing here can go stale when a year turns over. Where a date is set afresh each year instead, this catalogue leaves the event out rather than guess at it.

In 2027 it is a Monday. Across the next 10 years it lands on 7 different weekdays: Sunday 2 times, Monday 1 time, Tuesday 2 times, Wednesday 1 time, Thursday 2 times, Friday 1 time, Saturday 1 time. A fixed calendar date moves forward one weekday a year and two across a leap year, which is why the pattern takes twenty eight years to repeat.
