Temporal.PlainDate.prototype.yearOfWeek
Baseline Limited availability
This feature is not Baseline because it does not work in some of the most widely-used browsers.
The yearOfWeek accessor property of Temporal.PlainDate instances returns an integer representing the year to be paired with the weekOfYear of this date, or undefined if the calendar does not have a well-defined week system. It is calendar-dependent.
Usually this is the year of the date, but for ISO 8601, the first and last few days of the year may be attributed to the last week of the previous year or the first week of the next year, causing the yearOfWeek to differ by 1. See weekOfYear for more details.
The set accessor of yearOfWeek is undefined. You cannot change this property directly.
Examples
See the examples in the weekOfYear page.
