Input a formatted date(s) and convert to a timestamp using strtotime() or a similar function.
Then do math on the date(s) and use date() to format as needed.

There is no "default" way to do this, but depending on your needs, you can put together a combination of a few functions to accomplish any necessary math.

The only better method would be to write a function for yourself that automates the process, using those functions as the base.
