Temporal PlainDateTime
PlainDateTime combines a calendar date with a wall-clock time. It has no time zone until you supply one.
Where to run this
This example uses the JavaScript console playground. Select Run to execute it; the example does not run on this lesson page.
A practical example
if (typeof Temporal === "undefined") {
console.log("Temporal is not available in this runtime. Use a supporting browser or a reviewed local polyfill.");
} else {
const meeting = Temporal.PlainDateTime.from("2026-11-07T10:30");
console.log(meeting.add({minutes: 15}).toString());
}
What happens
The wall-clock value moves to 10:45 on the same date.
