Javascript date comparison ignoring timestamp value

Question

What is the simplest way to compare two dates neglecting the timestamps. I have got two dates firstDate coming from the database (converted into javascript date) and secondDate coming from a date picker input field.
Essentially for my algorithm these two dates are equal as it doesn't take timestamp into consideration but the code won't consider it equal as firstDate has 01:00:00 in it.
How to completely discard the timestamp for comparison?

firstDate:

Tue Mar 24 1992 01:00:00 GMT-0500 (Central Daylight Time)

secondDate:

Tue Mar 24 1992 00:00:00 GMT-0500 (Central Daylight Time)

Code:

   if(firstDate < secondDate) {

        alert("This alert shouldn't pop out as dates are equal");
    }

Answer 1

You could use toDateString to get rid of the the time, and reassign that to the firstDate and secondDate variables. There might be a better way, but this is what came to mind for me.

firstDate = new Date(firstDate.toDateString());
secondDate = new Date(secondDate.toDateString());
if(firstDate < secondDate){
    alert("This alert shouldn't pop out as dates are equal");
}

Also, you'll want to make sure you're comparing the values of the dates, and not checking if they're the same object when you compare if they're equal. So something like.

firstDate.valueOf() == secondDate.valueOf()
