// Represents a whole or partial calendar date, e.g. a birthday. The time of day
// and time zone are either specified elsewhere or are not significant. The date
// is relative to the Proleptic Gregorian Calendar. This can represent:
//
// * A full date, with non-zero year, month and day values
// * A month and day value, with a zero year, e.g. an anniversary
// * A year on its own, with zero month and day values
// * A year and month value, with a zero day, e.g. a credit card expiration date
//
// Related types are [google.type.TimeOfDay][google.type.TimeOfDay] and `google.protobuf.Timestamp`.
