Date

  • google.type.Date represents a calendar date, including full dates, month/day, year only, or year/month combinations.

  • It's based on the Gregorian Calendar and can be used for birthdays, anniversaries, and credit card expirations.

  • The JSON representation uses a simple object with year, month, and day integer fields.

  • Year values range from 1 to 9999, month from 1 to 12, and day from 1 to 31, with 0 allowed for specific cases.

  • Related types include google.type.TimeOfDay, google.type.DateTime, and google.protobuf.Timestamp.

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).
