Date/Time Difference Calculator

To calculate the difference between two dates and/or times of day,
enter a date and/or time into the two fields below
in almost any conventional date/time format.

Note for dates, m/d/y is correct, d/m/y is incorrect
Time format: hours:minute:seconds or hours:minutes
(ie. put a ':' between hrs, mins & secs)

This does not account for switching to/from
Daylight Savings Time within your specified date range (yet!)
