This behaviour is documented:

| The fuzz in units can cause problems with relative items. For example,
| `2003-07-31 -1 month' might evaluate to 2003-07-01, because 2003-06-31
| is an invalid date. To determine the previous month more reliably, you
| can ask for the month before the 15th of the current month. [...]
