How to compare only date in moment.js

I am new to moment.js. I have a date object and it has some time associated with it. I just want to check if that date is greater than or equal to today's date, excluding the time when comparing.

 var dateToCompare = 2015-04-06T18:30:00.000Z

I just want to check if dateToCompare is equal or greater than today's date. I have checked isSame of moment.js, but it seems to take string and only the date part. But I do not want to convert my date to string or manipulate it further. Because I am worried that javascript may do something unexpected when converting that date to string(like adding the offset or dst,etc), or may be I am wrong.

Sample isSame() from docs

moment('2010-10-20').isSame('2010-10-20');

Also I am looking for something like isSame() and isAfter() combined as one statement.

I need to compare using moment.js only.Please do not suggest plain javascript date comparison.

Solution 1:

The docs are pretty clear that you pass in a second parameter to specify granularity.

If you want to limit the granularity to a unit other than milliseconds, pass the units as the second parameter.

moment('2010-10-20').isAfter('2010-01-01', 'year'); // false
moment('2010-10-20').isAfter('2009-12-31', 'year'); // true

As the second parameter determines the precision, and not just a single value to check, using day will check for year, month and day.

For your case you would pass 'day' as the second parameter.

Solution 2:

Meanwhile you can use the isSameOrAfter method:

moment('2010-10-20').isSameOrAfter('2010-10-20', 'day');

Solution 3:

In my case i did following code for compare 2 dates may it will help you ...

var date1 = "2010-10-20";
var date2 = "2010-10-20";
var time1 = moment(date1).format('YYYY-MM-DD');
var time2 = moment(date2).format('YYYY-MM-DD');
if(time2 > time1){
	console.log('date2 is Greter than date1');
}else if(time2 > time1){
	console.log('date2 is Less than date1');
}else{
	console.log('Both date are same');
}

Solution 4:

You could use startOf('day') method to compare just the date

Example :

var dateToCompare = moment("06/04/2015 18:30:00");
var today = moment(new Date());

dateToCompare.startOf('day').isSame(today.startOf('day'));
