Not directly related to this, but it reminded me: the UK has (19th century,
if I recall correctly) case law about this topic. To be precise, what is
meant by statements like "three months after 31st March"?

The court decided that you move to the relevant month and, if it doesn't
have that day in it, step *back* to the last day of the month. So the
answer in that example is 30th June. And 31st March is never exactly a
month after any date.

So anyone born on 29th February reaches adulthood on 28th February 18 years
later.
