JavaScript Date Comparison

I am new to cheaper JavaScript functions and I need to compare two date objects, but within the hour range. For example, if Date1 is less than two hours before (or from) Date2. How can I do that?

The Date.UTC () method returns the number of milliseconds in a date string since midnight January 1, 1970, according to UTC. Get both UTC values ​​for dates, then subtract them. The result must be less than 3600000 (1000 * 60 * 60) by no more than one hour difference.

You can perform mathematical operations on Date objects, they are converted to integers. Highlighting two date objects will give you the difference in milliseconds. Two hours = 120 minutes = 7200 seconds = 7200000 milliseconds.



var d1 = new Date('5/13/2010 08:30');
var d2 = new Date('5/13/2010 10:00');

if( d2 - d1  < 7200000 ){
//less than two hours difference
}
