Temporal.PlainDate.prototype.subtract()

Limited availability

This feature is not Baseline because it does not work in some of the most widely-used browsers.

Experimental: This is an experimental technology
Check the Browser compatibility table carefully before using this in production.

The subtract() method of Temporal.PlainDate instances returns a new Temporal.PlainDate object representing this date moved backward by a given duration (in a form convertible by Temporal.Duration.from()).

If you want to subtract two dates and get a duration, use since() or until() instead.

Syntax

subtract(duration)
subtract(duration, options)

Parameters

duration

A string, an object, or a Temporal.Duration instance representing a duration to subtract from this date. It is converted to a Temporal.Duration object using the same algorithm as Temporal.Duration.from().

options Optional

An object containing the following property:

overflow Optional

A string specifying the behavior when a date component is out of range. Possible values are:

"constrain" (default): The date component is clamped to the valid range.
"reject": A RangeError is thrown if the date component is out of range.

Return value

A new Temporal.PlainDate object representing the date specified by the original PlainDate, minus the duration.

Description

Subtracting a duration is equivalent to adding its negation, so all the same considerations apply.

Exceptions

RangeError: Thrown if the result is not in the representable range, which is ±(10⁸ + 1) days, or about ±273,972.6 years, from the Unix epoch.

Examples

Subtracting a duration

const start = Temporal.PlainDate.from("2022-01-01");
const end = start.subtract({ years: 1, months: 2, weeks: 3, days: 4 });
console.log(end.toString()); // 2020-10-07
