As date calculation is far more difficult than it seems at first glance, leap years every 4 year and every 100 etc, but also leap seconds if you really get into it, and then the different calendars that people used and some still use not to forget the timezones that you might need to take into account. All in all it could become quite messy. I would therefore advise to always look for a module that fits with the calcualtions you are going to be doing and the type/format of date data that you are going to be processing. There is to my knowledge not a single module that does it all, but pretty much all possible scenario's have been solved so shop around a bit I'm sure you will find what you are looking for.
