Is After

This indicates whether the Day.js object is after the other supplied date-time.

dayjs().isAfter(dayjs('2011-01-01')); // default milliseconds

If you want to limit the granularity to a unit other than milliseconds, pass it as the second parameter. In that case the comparision respects the given unit and the units above.

dayjs().isAfter('2011-01-01', 'month'); // compares month and year

Units are case insensitive, and support plural and short forms.
