This is THE app for doing arithmetic with times and dates. Two ways in which it works:
1. Add/subtract/multiply days/hour/minutes and seconds
2. Calculate how long between two dates or what the date will be after some period of time.
Customisable, easy to use, intuitive, its what you need if you want to easily do arithmetic with time. Dates and times are easy to enter using either the 12 or 24 hour clock. The look of the app is easily changed. Want more decimal places? No problem! Bigger font on the screen? Its yours!
If you work with dates a long time ago, the app knows about the Julian and Gregorian calendars. The dates these changed can be changed too!
