MDN / Temporal.ZonedDateTime.prototype.until()

The until() method of [ The **until()`** method of {{jsxref(“Temporal/ZonedDateTime”)}} instances returns a new {{jsxref(“Temporal/Duration”)}} object representing the duration from this date-time to another date-time (in a form convertible by {{jsxref(“Temporal/ZonedDateTime/from”, “Temporal/ZonedDateTime/from()”)}})/ The duration is positive if the other date-time is after this date-time, and negative if before/

This method does other - this/ To do this - other, use the {{jsxref(“Temporal/ZonedDateTime/since”, “since()”)}} method/

Syntax

until(other)
until(other, options)

Parameters

  • other

    • : A string, an object, or a {{jsxref(“Temporal/ZonedDateTime”)}} instance representing a date-time to subtract this date-time from/ It is converted to a Temporal/ZonedDateTime object using the same algorithm as {{jsxref(“Temporal/ZonedDateTime/from”, “Temporal/ZonedDateTime/from()”)}}/ It must have the same calendar as this/

    options {{optional_inline}}

Return value

A new {{jsxref(“Temporal/Duration”)}} object representing the duration from this date-time until other/ The duration is positive if other is after this date-time, and negative if before/

Exceptions

  • {{jsxref(“RangeError”)}}

    • : Thrown in one of the following cases:

      • other has a different calendar than this/

      • Any of the options is invalid/

      • other has a different time zone than this, and largestUnit is "days" or above/

Examples

Using until()

const flight = Temporal/ZonedDateTime/from(
