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 month accessor property of Temporal.PlainYearMonth instances returns a positive integer representing the 1-based month index in the year of this year-month. 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.PlainYearMonth object with the desired new value.
For general information and more examples, see Temporal.PlainDate.prototype.month.

Using month
const ym = Temporal.PlainYearMonth.from("2021-07"); // ISO 8601 calendar
