A reminder that repeats on the 31st. What should it do in February?
The 28th is easy. March is where it goes wrong, because if the reminder only remembers its last date, rather than the day you picked, it stays on the 28th for good. Mine did, until this week.
Catchlight now keeps the day you chose, so it runs 31 January, 28 February, 31 March, 30 April.
A yearly one set for 29 February 2028 does the same, the 28th for three years and the 29th again in 2032.
