If you're trying to determine a person's birthdate, use this tool to calculate a range for each event where their age was reported. This may help eliminate many of the dates in the range of dates initially calculated. A printable worksheet for comparing the results can be found here.

If you know the exact number of years, months and days before an event, use the Time Deductor.

To calculate the amount of time between two dates, use the Time Calculator.
