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.

The inLeapYear accessor property of Temporal.PlainYearMonth instances returns a boolean indicating whether this year-month is in a leap year. A leap year is a year that has more days (due to a leap day or leap month) than a common year. It is calendar-dependent.

A `Duration` type to represent a span of time, typically used for system timeouts.

A measurement of a monotonically nondecreasing clock. Opaque and useful only with `Duration`.

The month accessor property of Temporal.ZonedDateTime instances returns a positive integer representing the 1-based month index in the year of this date. The first month of this year is 1, and the last month is the monthsInYear. It is calendar-dependent.

The eraYear accessor property of Temporal.ZonedDateTime instances returns a non-negative integer representing the year of this date within the era, or undefined if the calendar does not use eras (e.g., ISO 8601). The year index usually starts from 1 (more common) or 0, and years in an era can decrease with time (e.g., Gregorian BCE). era and eraYear together uniquely identify a year in a calendar, in the same way that year does. It is calendar-dependent.
