Temporal.PlainDateTime.prototype.year

The year accessor property of {{jsxref("Temporal.PlainDateTime")}} instances returns an integer representing the number of years of this date relative to the start of a calendar-specific epoch year. It is calendar-dependent.

The set accessor of year is undefined. You cannot change this property directly. Use the {{jsxref("Temporal/PlainDateTime/with", "with()")}} method to create a new Temporal.PlainDateTime object with the desired new value.

For general information and more examples, see {{jsxref("Temporal/PlainDate/year", "Temporal.PlainDate.prototype.year")}}.
