The equals() method of Temporal.PlainMonthDay instances returns true if this month-day is equivalent in value to another month-day (in a form convertible by Temporal.PlainMonthDay.from()), and false otherwise. They are compared both by their underlying ISO date values and their calendars.

The withCalendar() method of Temporal.PlainDateTime instances returns a new Temporal.PlainDateTime object representing this date-time interpreted in the new calendar system. Because all Temporal objects are designed to be immutable, this method essentially functions as the setter for the date-time's calendarId property.

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 daysInWeek accessor property of Temporal.PlainDateTime instances returns a positive integer representing the number of days in the week of this date. It is calendar-dependent.

The toZonedDateTimeISO() method of Temporal.Instant instances returns a new Temporal.ZonedDateTime object representing this instant in the specified time zone using the ISO 8601 calendar system.

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.
