What"s the best way to calculate date difference in Javascript



I doing a function in Javascript like the VisualBasic DateDiff.





You give two dates and the returning time interval (Seconds, Minutes, Days, etc...)







DateDiff(ByVal Interval As Microsoft.VisualBasic.DateInterval, _

ByVal Date1 As Date, ByVal Date2 As Date) as Long







So what's the best way to calculate the difference of Javascript Dates?

  1. Use the Date object like so:

    function DateDiff(var /*Date*/ date1, var /*Date*/ date2) {
    return date1.getTime() - date2.getTime();
    }


    This will return the number of milliseconds difference between the two dates. Converting it to seconds, minutes, hours etc. shouldn't be too difficult.

  2. If you follow this tutorial, one way is to use:

    Date.getTime()


    You will find a full javascript function here, complete with date validation.
