javascript instance accessor property
Temporal.PlainDate.prototype.daysInWeek
The daysInWeek accessor property of 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
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
