The minute accessor property of Temporal.ZonedDateTime instances returns a integer from 0 to 59 representing the minute component of this time.

The set accessor of minute is undefined. You cannot change this property directly. Use the with() method to create a new Temporal.ZonedDateTime object with the desired new value.

For general information and more examples, see Temporal.PlainTime.prototype.minute.

For ZonedDateTime, minute can be non-continuous due to offset changes. While much rarer than hour changes (because daylight saving time shifts are usually by whole hours), it can still happen.

Examples

Using minute

const dt = Temporal.ZonedDateTime.from(
  "2021-07-01T12:34:56.123456789-04:00[America/New_York]",
);
console.log(dt.minute); // 34

Non-continuous minute

Typically, minute always goes from 0 to 59 and then back to 0, even when passing through a daylight saving time transition. There's one particular case where DST has a 30-minute offset: Lord Howe Island in Australia, which shifts between +10:30 and +11:00. In this case, the minute can be non-continuous.

const dt = Temporal.ZonedDateTime.from(
  "2021-10-03T01:59:00+10:30[Australia/Lord_Howe]",
);
console.log(dt.minute); // 59
const dt2 = dt.add({ minutes: 1 });
console.log(dt2.minute); // 30
console.log(dt2.toString()); // 2021-10-03T02:30:00+11:00[Australia/Lord_Howe]

There's a second peculiar case where the minute can be non-continuous: the standardization of hourly time zones. In the early 20th century, most countries were using their own time zones which were often not a whole hour offset from UTC. For example, Paris used to have an offset of UTC+0:09:21, which was changed to UTC+0 on March 11, 1911.

const dt = Temporal.ZonedDateTime.from(
  "1911-03-10T23:59:00+00:09:21[Europe/Paris]",
);
console.log(dt.minute); // 59
const dt2 = dt.add({ minutes: 1 });
console.log(dt2.minute); // 50
console.log(dt2.toString()); // 1911-03-10T23:50:39+00:00[Europe/Paris]

For this reason, you should always prefer add() and subtract() to manipulate dates and times, rather than directly changing the minute property.
