Is Between

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

TIP

This requires the IsBetween plugin to work

dayjs.extend(isBetween);
dayjs('2010-10-20').isBetween('2010-10-19', dayjs('2010-10-25'));
// default milliseconds

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

dayjs().isBetween('2010-10-19', '2010-10-25', 'month'); // compares month and year

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

The fourth parameter is about inclusivity. A [ indicates inclusion of a value. A ( indicates exclusion.

If the inclusivity parameter is used, both indicators must be passed.

dayjs('2016-10-30').isBetween('2016-01-01', '2016-10-30', null, '[)');
