-Subject: [PATCH 2/2] Fix the 6-days-until-the-end-of-the-month bug
-
-The addition causes the date to shift
-forward into 1st of the next month, because a 0-based offset
-is compared to be "more than" the days in the month instead of "more than
-or equal to".
-
-This is triggered by corner-cases where transition date is 6 days
-off the end of the month and our calculations put it at N+1th day of the
-month (where N is the number of days in the month). The subtraction should
-be triggered to move the date back a week, putting it 6 days off the end;
-for example, October 25 for CET DST transition; but due to incorrect comparison
-the date isn't shifted back, we add 31 days to October 1st and end up
-at November 1st).
-
-Fixes issue #2215.
