Then you need a date. I would break the datetime into a date and a time, then do the months stuff to the date, then compose a new datetime from the result. >Anyway, the use of calendar.monthrange simplifies the task a lot. Hmm, yes it would. The important thing to remember about any solutions mentioned is that dates and datetimes have different semantics. Specificly, you can't add fixed elapsed times such as seconds to do "calendar like" arithmetic, which works in days etc because months have varying numbers of days, and days have varying numbers of seconds (not merely the odd leap second but also the horrors of timezones and summer/winter time shifts). So working with the calendar component (days upwards) is a meaningful thing. But working in, say, seconds with the _bjective_ of doing days or months is nearly pointless.
