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

The nanosecond accessor property of Temporal.ZonedDateTime instances returns a integer from 0 to 999 representing the nanosecond (10-9 second) component of this time.

The monthsInYear accessor property of Temporal.PlainDate instances returns a positive integer representing the number of months in the year of this date. It is calendar-dependent.

The toString() method of Temporal.PlainYearMonth instances returns a string representing this year-month in the RFC 9557 format.

The Temporal.PlainYearMonth.from() static method creates a new Temporal.PlainYearMonth object from another Temporal.PlainYearMonth object, an object with year and month properties, or an RFC 9557 string.

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

The valueOf() method of Temporal.PlainYearMonth instances throws a TypeError, which prevents Temporal.PlainYearMonth instances from being implicitly converted to primitives when used in arithmetic or comparison operations.

The Symbol.isConcatSpreadable static data property represents the well-known symbol Symbol.isConcatSpreadable. The Array.prototype.concat() method looks up this symbol on each object being concatenated to determine if it should be treated as an array-like object and flattened to its array elements.
