Date Time Calc is a small utility able to calculate future and past dates using a given time interval from an assigned date 'Date Guess' and also 'Date Difference' between dates (even with precision to hours, minutes, seconds)


Date Time Calc is intended for users needing to calculate expected dates after a specific number of days as in a typical business use (example of periods often used in business: 15, 30, 60, 90, 120 or 150 days)
or to know the exact time interval between two specific dates and time 'Time difference' often needed in technical fields or for business contracts.

The dates can be selected using standard calendar controls
Time interval is expressed in days or in a more precise way also using hours, minutes and seconds
Result is re-visualized in a 'clear readable way' in the lower part of the window to avoid wrong interpretation of the results

Fully Mac OS X 10.7 Lion compatible.
Optimized for OS X 10.8 Mountain Lion

Lawyers: Yes!!! - The one thing I missed from WinWoes days = a decent date calculator. I was sooo glad to see this that I immediately hit the buy button. **NO** regrets. This is sweet and simple, doing exactly what is needed, in a completely no fuss manner. Given that the app is perfectly described, and acts accordingly, 5 stars. But to reach true "gem" status, there should be a default option or some way to retain the middle screen's set options (e.g. # of days) between launches. (Note: Apparently, no shortcut key to call it up, but LaunchBar cured that problem! Now a quick command-shift-D gets me to the main screen. Loving it!!)

Date and Time Calc That Does Just That: Easily! Buy It! - Love it. Just what I needed. The price you pay for this app is more than worth the time you save using it.
