Sometimes I find myself running into all sorts of strange problems that require more than just a “back of the napkin” scribbling. As always, these edge conditions drive me to come up with a solution that’s handy. And hopefully handy for others.

In just about everything I’ve done, there has at some point been a need to do arbitrary date calculations. DateSpanner helps remedy that. It’s a small, free app that I have made to make it very easy to figure out arbitrary dates based on a given span of time.
