The month accessor property of Temporal.ZonedDateTime instances returns a positive integer representing the 1-based month index in the year of this date. The first month of this year is 1, and the last month is the monthsInYear. It is calendar-dependent.

The set accessor of month 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.PlainDate.prototype.month.

Examples

Using month

const dt = Temporal.ZonedDateTime.from("2021-07-01[America/New_York]"); // ISO 8601 calendar
console.log(dt.monthCode); // "M07"
console.log(dt.month); // 7
