Perform simple date calculations including:
* Add and subtract days from a date
* Determine number of days or weeks between dates

This project began as a request from my wife to help the nurses at her practice. They were counting out dates for shots, follow up appointments, etc on the calendar. She asked me to make an app that would do it for them.

It is open source and available on github: https://github.com/doyleyoung/IosDayToDay
