How precise do you need to be?

For example: if one point is 9:00PM Feb. 27, 2016 and the next is 8:00AM March 1, 2016, you will need to account for leap year, adding one day.

Accuracy to the hour? or to the minute?

To get the difference in number of days from one day to another, look at the actions DateToNum & NumToDate

From Helpfile:


Convert a formatted date to a number that can be used in mathematical calculations. The result, a numeric date, represents the number of days since December 30, 1899. A numeric date can be converted back into a formatted date with the NumToDate Action.


DateToNum "date" "format" "variable"


A formatted date consisting of two or three numbers, separated by “\”, “/” or “-”. Year values between 0 and 99 are assumed to be in the current century. The date must match the format parameter below.

A string that identifies the format of the date. For example:




Use the system’s default date format.


The name of the variable to store the converted date number.

The following example calculates the number of days since December 15th, 2004:

DateToNum "12/15/2004" "m/d/y" "[StartDate]"
DateToNum "[DateShort]" "Default" "[Today]"
Math "[Today]-[StartDate]" "0" "[Result]"
AlertBox "Answer" "It has been [Result] days since 12/15/2004"

You can then s convert days to hours/minutes and find the difference in hours within the day between the two times.
