Question

Say we have 2 Date objects in Javascript;

var d1 = new Date('...');
var d2 = new Date('...');

We do a comparison:

d1 < d2;

This comparison will always take into account hours, minutes, seconds.

I want it to only take into account the year, month and date for comparison.

What’s the easiest way to do this?

jQuery is allowed aswell.

Answer 1

Reset the hours, minutes, seconds, and milliseconds:

var d1 = new Date();
d1.setHours(0);
d1.setMinutes(0);
d1.setSeconds(0);
d1.setMilliseconds(0);

Or using setHours, which is less verbose:

var d1= new Date();
d1.setHours(0, 0, 0, 0);

And finally, to compare if the resulting Dates are the same use getTime():

d1.getTime() == d2.getTime()
