This calculator requires the use of Javascript enabled and capable browsers. This calculator determines the number of weeks, days, hours, minutes and seconds between a day and any other day. It utilizes the standard Gregorian calendar. Thus, century years are leap years only if divisible by 400. There is validity testing to verify that the target date is a valid one. Enter both dates (mm/dd/yyyy) and time (hh:mm:ssa) information and click on Calculate. The seconds are optional and the am/pm indicator is not needed if both times are 24 hour format. The information returned is the difference of the two different date/time entries.
