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).
Year of the date. Must be from 1 to 9999, or 0 to specify a date without a year.

[null,null,["Last updated 2025-08-20 UTC."],[],["This schema defines a calendar date using the Gregorian Calendar, representing full dates or partial dates. Key actions include specifying a `year` (1-9999, or 0), `month` (1-12, or 0), and `day` (1-31, or 0). A zero value in `year`, `month`, or `day` indicates that the field is not relevant. The format represents full dates, month/day pairs, year-only, or year/month combinations. It is related to `TimeOfDay`, `DateTime`, and `Timestamp`.\n"]]
