Temporal.PlainDate.prototype.yearOfWeek
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 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.
