Temporal.PlainDateTime()

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 Temporal.PlainDateTime() constructor creates Temporal.PlainDateTime objects.

This constructor allows you to create instances by directly supplying the underlying data. Like all other Temporal classes, you should usually construct Temporal.PlainDateTime objects using the Temporal.PlainDateTime.from() static method, which can handle a variety of input types.

Syntax

js
new Temporal.PlainDateTime(year, month, day)
new Temporal.PlainDateTime(year, month, day, hour)
new Temporal.PlainDateTime(year, month, day, hour, minute)
new Temporal.PlainDateTime(year, month, day, hour, minute, second)
new Temporal.PlainDateTime(year, month, day, hour, minute, second, millisecond)
new Temporal.PlainDateTime(year, month, day, hour, minute, second, millisecond, microsecond)
new Temporal.PlainDateTime(year, month, day, hour, minute, second, millisecond, microsecond, nanosecond)
new Temporal.PlainDateTime(year, month, day, hour, minute, second, millisecond, microsecond, nanosecond, calendar)

Note: Temporal.PlainDateTime() can only be constructed with new. Attempting to call it without new throws a TypeError.

Parameters

year

A number, truncated to an integer, representing the year in the ISO calendar system.

month

A number, truncated to an integer, representing the month in the ISO calendar system.

day

A number, truncated to an integer, representing the day of the month in the ISO calendar system.

hour Optional

A number, truncated to an integer, representing the hour component.

minute Optional

A number, truncated to an integer, representing the minute component.

second Optional

A number, truncated to an integer, representing the second component.

millisecond Optional

A number, truncated to an integer, representing the millisecond component.

microsecond Optional

A number, truncated to an integer, representing the microsecond component.

nanosecond Optional

A number, truncated to an integer, representing the nanosecond component.

calendar Optional

A string representing the calendar to use. Note that irrespective of the calendar, the year, month, and day must be in the ISO 8601 calendar system. Defaults to "iso8601".

Return value

A new Temporal.PlainDateTime object, representing the date-time specified by the parameters.

Exceptions

RangeError

Thrown in one of the following cases:

  • Any date-time component is not a finite number.
  • The date-time component combination does not represent a valid date in the ISO calendar system, or is not in the representable range, which is ±(108 + 1) days, or about ±273,972.6 years, from the Unix epoch.
  • calendar is not a valid calendar identifier.

Examples

Using Temporal.PlainDateTime()

js
const dt = new Temporal.PlainDateTime(2021, 7, 1);
console.log(dt.toString()); // 2021-07-01T00:00:00

const dt2 = new Temporal.PlainDateTime(2021, 7, 1, 0, 0, 0, 0, 0, 0, "hebrew");
console.log(dt2.toString()); // 2021-07-01T00:00:00[u-ca=hebrew]
