Moment: Get last day of the month?

I guess for now this works:
moment().add('months', 1).date(1).subtract('days', 1)

Also, the setters overflow if they are out of range.

moment().date(0); // the last day of last month
moment().date(-1); // the second to last day of last month
moment().hours(25); // 1 am the next day

So you could do something like this...

moment().add('months', 1).date(0);

moment().endOf('month');

works since 1.7

moment().endOf('month');

or

moment(year-month-day).endOf('month');

@lance-ding Thanks! That's was definitely helpful.

I still think it would be nice to have a .format() option for the number of days in the current month.

Related: you can also use moment().daysInMonth() to get an integer representing the last day in the month.

Deprecation warning:
moment().add(period, number) is deprecated. Please use moment().add(number, period).

So a little change to the code would be: moment().add(1, 'months').date(1).subtract('days', 1)

@gideonapollob , yep. You would need to reverse in your .subtract() as well.

But .endOf() is almost for sure the best choice for what you're doing.

You may get last day of month. like this.

moment(2017-10).endOf('month').format('DD')

which shows last month last date

moment().subtract(1, 'months').endOf('month').format('DD-MM-YYYY')
