Temporal.PlainDate.prototype.daysInWeek
Limited availability
This feature is not Baseline because it does not work in some of the most widely-used browsers.
The daysInWeek accessor property of Temporal.PlainDate instances returns a positive integer representing the number of days in the week of this date. It is calendar-dependent.
For the ISO 8601 calendar, this is always 7, but in other calendar systems it may differ from week to week. All commonly supported calendars use 7-day weeks.
The set accessor of daysInWeek is undefined. You cannot change this property directly.
Examples
Using daysInWeek
js
const date = Temporal.PlainDate.from("2021-07-01");
console.log(date.daysInWeek); // 7
const date2 = Temporal.PlainDate.from("2021-07-01[u-ca=chinese]");
console.log(date2.daysInWeek); // 7
