The subtract() method of Temporal.ZonedDateTime instances returns a new Temporal.ZonedDateTime object representing this date-time moved backward by a given duration (in a form convertible by Temporal.Duration.from()).

The weekOfYear accessor property of Temporal.PlainDate instances returns a positive integer representing the 1-based week index in the yearOfWeek of this date, or undefined if the calendar does not have a well-defined week system. The first week of the year is 1. It is calendar-dependent.

The calendarId accessor property of Temporal.PlainMonthDay instances returns a string representing the calendar used to interpret the internal ISO 8601 date.

The since() method of Temporal.ZonedDateTime instances returns a new Temporal.Duration object representing the duration from another date-time (in a form convertible by Temporal.ZonedDateTime.from()) to this date-time. The duration is positive if the other date-time is before this date-time, and negative if after.

The dayOfYear accessor property of Temporal.PlainDate instances returns a positive integer representing the 1-based day index in the year of this date. The first day of this year is 1, and the last day is the daysInYear. 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 millisecond accessor property of Temporal.PlainTime instances returns an integer from 0 to 999 representing the millisecond (10-3 second) component of this time.

The timeZoneId accessor property of Temporal.ZonedDateTime instances returns a string representing the time zone identifier used to interpret the internal instant. The string is either a named identifier in the preferred case (such as "America/New_York"), or an offset in the form "±hh:mm". If the time zone has aliases, the timeZoneId is the identifier used to create the ZonedDateTime, without canonicalization to the primary identifier.

The minute accessor property of Temporal.PlainTime instances returns an integer from 0 to 59 representing the minute component of this time.
