Time: Add and Subtract Percent

A time span in days, hours, minutes and seconds plus or minus x percent gives another time span. Please enter a span and a percentage to add or subtract and press Calculate. Result as start time makes the calculation again with the previous result.

Example: when you add 30 percent to 2 days and 6 hours, you get 2 days, 22 hours and 12 minutes. If 30 percent are subtracted, 1 day, 13 hours and 48 minutes remain.
