Temporal.PlainDateTime.prototype.day
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 day accessor property of Temporal.PlainDateTime instances returns a positive integer representing the 1-based day index in the month of this date, which is the same day number you would see on a calendar. It is calendar-dependent.
The set accessor of day is undefined. You cannot change this property directly. Use the with() method to create a new Temporal.PlainDateTime object with the desired new value.
For general information and more examples, see Temporal.PlainDate.prototype.day.
Examples
Using day
js
const dt = Temporal.PlainDateTime.from("2021-07-01"); // ISO 8601 calendar
console.log(dt.day); // 1
