DateCalc, the new and improved date difference calculator has an improved user interface utilizing unique time input format, which allows one to pinpoint a specific time.
This way you can for example calculate what date and time it is five weeks and 2889 minutes after the day which was two weeks and three day before your birthday noon.

In time input format this would look like:
5W + 2889m + (197405201200) - 2W - 3D

In plain english the above would read "Take five weeks (5W), add 2889 minutes (2889m) to it. Add this amount of time to the date which was 20th of May, 1974 at 12 oclock (197405201200). From the result go back two weeks (2W) three days (3D)", and DateCalc lets you see that correct date is 06/09/03 and time is 12:09
