Enum std.datetime.AllowDayOverflow
In some date calculations, adding months or years can cause the date to fall
on a day of the month which is not valid (e.g. February 29th 2001 or
June 31st 2000). If overflow is allowed (as is the default), then the month
will be incremented accordingly (so, February 29th 2001 would become
March 1st 2001, and June 31st 2000 would become July 1st 2000). If overflow
is not allowed, then the day will be adjusted to the last valid day in that
month (so, February 29th 2001 would become February 28th 2001 and
June 31st 2000 would become June 30th 2000).
AllowDayOverflow only applies to calculations involving months or years.
