Date

  • A Date object represents a whole or partial calendar date, relative to the Gregorian Calendar, without a time of day or time zone.

  • A Date object can represent a full date, a month and day, a year, or a year and month.

  • The JSON representation of a Date object includes integer fields for year, month, and day.

  • The year field can be 0 to represent a date without a year, and must be between 1 and 9999 otherwise.

  • The month field can be 0 to represent a year without a month and day, and must be between 1 and 12 otherwise.

  • The day field can be 0 to represent a year by itself or a year and month where the day isn't significant, and must be between 1 and 31 otherwise, and valid for the given year and month.

Represents a whole or partial calendar date, such as a birthday. The time of day and time zone are either specified elsewhere or are insignificant. The date is relative to the Gregorian Calendar. This can represent one of the following:

  • A full date, with non-zero year, month, and day values.
  • A month and day, with a zero year (for example, an anniversary).
  • A year on its own, with a zero month and a zero day.
  • A year and month, with a zero day (for example, a credit card expiration date).
