Radioactive Decay Time Calculator

The time calculator allows you to determine:

  • the number of days between two dates
  • the result of adding or subtracting a number of days to a date

To use:

Enter the dates in the textboxes provided. The order that they are entered does not matter as the value returned is the absolute value of the difference. You can enter dates in either the mm/dd/yyyy or the Mmm dd, yyyy format (i.e. 11/27/96 or Nov 27, 1996). You can also use yy instead of yyyy if the year is in the 1900's. If the result is in the 1900's, it is returned in the yy fashion. If mm/dd/yy is actually entered, the default value of Jan 1, 1970 is used.
