Javascript Get the time difference between 2 dates

Question

Okay so what i'm trying to do is get the time values between 2 different dates.

For example:

date1 = 3/2/2014 - 14:12

date2 = 4/2/2014 - 16:22

How would I get the time difference between date1 and date2? (26hrs, 10mins) <- that would be the perfect output for what I want.

I've had a look at the parse method and if I understand it correctly, I think I could make that work by doing something like:

myDate = date1;

myDate.parse(date2);

then convert the output to how I wanted it from there, but I haven't seen any examples where it takes the time of day into consideration.

You could use the Date class and then just subtract the 2 dates

var difference = ( new Date(2014, 2, 4, 16, 22, 0).getTime()
                   - new Date(2014, 2, 3, 14, 12, 0).getTime()
                 ) / 1000

getTime() gives you the time in milliseconds, so you have to divide by 1000 to get the result in seconds.

You just need to subtract the two Date object to get the difference since JavaScript will convert it to the right type automatically:

date1 - date2  //difference in milliseconds

For formatting, you can set up a function similar to this:

Number.prototype.format = function(){
    return [
        (this/86400|0), "days",
        (this/3600|0) % 24 , "hours",
        (this/60|0) % 60 , "minutes",
        (this|0) % 60 , "seconds"
    ].join(" ");
};

((date1 - date2)/1000).format();  //Formatted string
