The until() method of Temporal.PlainDate instances returns a new Temporal.Duration object representing the duration from this date to another date (in a form convertible by Temporal.PlainDate.from()). The duration is positive if the other date is after this date, and negative if before.

This method does other - this. To do this - other, use the since() method.

Syntax

until(other)
until(other, options)

Parameters

other

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

options Optional

The same options as since().

Return value

A new Temporal.Duration object representing the duration from this date until other. The duration is positive if other is after this date, and negative if before.

Exceptions

RangeError

Thrown in one of the following cases:

• other has a different calendar than this.
• Any of the options is invalid.

Examples

Using until()

const launch = Temporal.PlainDate.from("2035-01-01");
const now = Temporal.Now.plainDateISO();
const duration = now.until(launch);
console.log(`It will be ${duration.toLocaleString("en-US")} until the launch`);
