Duration Calculator

This calculator is able to calculate a target date on the basis of a duration or a duration on the basis of a target date. Besides the calculation based on calendar days, the calculation can also be changed to working days (Monday to Friday). In this case, only the calculation of the target date is available. In the calculation of working days, a german federal land may be selected to take holidays into account.

The base date is the mandatory for all calculations.

You can enter any duration in the duration fields in order to calculate the target date. Alternatively, you can enter any date in the target date field in order to calculate the duration between the base date and the target date. You can use negative duration values if you intend to calculate a target date which is before the base date.
