### what happens in google calendar if you repeat task monthly at 31st day of 
month and the next month has fewer days?


If you set a task to repeat monthly on the 31st day of the month in Google 
Calendar, and the next month has fewer days (e.g., February or some months with 
30 days), the task will fall on the last day of that month.


It is the same as the change proposed in the POLL.

We ought to have a switch to the existing behaviour, but I do not think
that we need it per-file or per-timestamp. If we do need such
granularity, it implies that some people actually prefer the existing
behaviour - something we are yet to hear in the replies to this poll.

This also picks the closest existing date - the change we propose in
this POLL.
