Temporal.PlainTime.prototype.hour

The hour accessor property of {{jsxref("Temporal.PlainTime")}} instances returns an integer from 0 to 23 representing the hour component of this time.

The set accessor of hour is undefined. You cannot change this property directly. Use the {{jsxref("Temporal/PlainTime/with", "with()")}} method to create a new Temporal.PlainTime object with the desired new value.

Examples#

Using hour#

const time = Temporal.PlainTime.from("12:34:56");
console.log(time.hour); // 12

Changing hour#

const time = Temporal.PlainTime.from("12:34:56");
const newTime = time.with({ hour: 15 });
console.log(newTime.toString()); // 15:34:56

You can also use {{jsxref("Temporal/PlainTime/add", "add()")}} or {{jsxref("Temporal/PlainTime/subtract", "subtract()")}} to move a certain number of hours from the current time.

const time = Temporal.PlainTime.from("12:34:56");
const newTime = time.add({ hours: 3 });
console.log(newTime.toString()); // 15:34:56
