GREAT App, very handy

I'm bad at doing date and time calculations. They are cumbersome and tedious. I use an Excel spreadsheet to make the calculations much easier.

Then I discovered "Time Calc: durations and dates". It is GREAT! This app is much easier to use than the spreadsheet, and can do much more. It has a pretty short learning curve.

Great for:
- Calculating the number of days between two dates. Or the number of hours, minutes, seconds, etc.
- Adding up total minutes and seconds of MP3 tracks to fit on a CD.
- Converting one time measure to another: X hours = how many days, weeks, minutes, seconds, hours by pressing just one key.

Nice GUI, very handy, highly recommended.
