But it is a fact that 21st June (on the modern calendar) is always the

shortest.

No-one says 21st June isn't the longest day. However, 24 June is known
as Midsummers Day. There is a difference.

As I said earlier in the thread 24th June "Midsummer Day" is a Quarter
Day, one of four (surprise!) on which, traditionally, bills are paid.

See (for example) http://www.pbenyon.plus.com/Misc/Quarter_days.html

Though I still don't agree with the Quarter days being the beginnings
of the four seasons.
