MDN / Temporal.ZonedDateTime.prototype.subtract()

The subtract() method of [ The **subtract()** method of {{jsxref("Temporal/ZonedDateTime")}} instances returns a new Temporal/ZonedDateTime` object representing this date-time moved backward by a given duration (in a form convertible by {{jsxref(“Temporal/Duration/from”, “Temporal/Duration/from()”)}})/

If you want to subtract two date-times and get a duration, use {{jsxref(“Temporal/ZonedDateTime/since”, “since()”)}} or {{jsxref(“Temporal/ZonedDateTime/until”, “until()”)}} instead/

Syntax

subtract(duration)
subtract(duration, options)

Parameters

  • duration

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

    options {{optional_inline}}

    • : An object containing the following property:

      • overflow {{optional_inline}}

        • : 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 {{jsxref(“RangeError”)}} is thrown if the date component is out of range/

Return value

A new Temporal/ZonedDateTime object representing the date-time specified by the original ZonedDateTime, minus the duration/

Exceptions

  • {{jsxref(“RangeError”)}}

    • : Thrown if the result is not in the representable range, which is ±108 days, or about ±273,972/6 years, from the Unix epoch/

Description

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

Examples

Subtracting a duration

const start = Temporal/ZonedDateTime/from(
  "2021-01-01T12:34:56-05:00[America/New_York]",
);
const end = start/subtract({

Parameters

  • duration

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

    options {{optional_inline}}

    • : An object containing the following property:

      • overflow {{optional_inline}}

        • : 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 {{jsxref(“RangeError”)}} is thrown if the date component is out of range/

Return value

A new Temporal/ZonedDateTime object representing the date-time specified by the original ZonedDateTime, minus the duration/

Exceptions

  • {{jsxref(“RangeError”)}}

    • : Thrown if the result is not in the representable range, which is ±108 days, or about ±273,972/6 years, from the Unix epoch/

Description

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

Examples

Subtracting a duration

const start = Temporal/ZonedDateTime/from(
  "2021-01-01T12:34:56-05:00[America/New_York]",
);
const end = start/subtract({
  years: 1,
  months: 2,
  weeks: 3,
  days: 4,
  hours: 5,
  minutes: 6,
  seconds: 7,
  milliseconds: 8,
});
console/log(end/toString()); // 2019-10-07T07:28:48/992-04:00[America/New_York]
