did you know you can celebrate any holiday a second time 11 days later if you just prefix the holiday name with “Old”
(the Gregorian calendar, at time of introduction, was 10 days off from the Julian. the English-speaking world was so slow to it that it became 11. certain things, like tax days, kept their “old” dates by advancing them forward 11 days, so that people wouldn’t be swindled.
the 11 day offset was fixed in stone at this time. it does not accommodate further divergence between the calendar systems.)
