Soren, If you are only using it for short period such as 7-30 days, it would be possible to simple handle "Decembers" differently to fix the year problem. Or make use of the days operator.
Other date tools exist, perhaps review Eric's powerful http://tiddlytools.com/timer.html or Evans formulae plugin.
