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).

Related types:



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



Month of a year. Must be from 1 to 12, or 0 to specify a year without a month and day.



Day of a month. Must be from 1 to 31 and valid for the year and month, or 0 to specify a year by itself or a year and month where the day isn't significant.


Represents civil time (or occasionally physical time).

This type can represent a civil time in one of a few possible ways:

  • When utc_offset is set and time_zone is unset: a civil time on a calendar day with a particular offset from UTC.
  • When time_zone is set and utc_offset is unset: a civil time on a calendar day in a particular time zone.
  • When neither time_zone nor utc_offset is set: a civil time on a calendar day in local time.

The date is relative to the Proleptic Gregorian Calendar.

If year, month, or day are 0, the DateTime is considered not to have a specific year, month, or day respectively.

This type may also be used to represent a physical time if all the date and time fields are set and either case of the time_offset oneof is set. Consider using Timestamp message for physical time instead. If your use case also would like to store the user's timezone, that can be done in another field.

This type is more flexible than some applications may want. Make sure to document and validate your application's limitations.



Optional. Year of date. Must be from 1 to 9999, or 0 if specifying a datetime without a year.



Optional. Month of year. Must be from 1 to 12, or 0 if specifying a datetime without a month.



Optional. Day of month. Must be from 1 to 31 and valid for the year and month, or 0 if specifying a datetime without a day.



Optional. Hours of day in 24 hour format. Should be from 0 to 23, defaults to 0 (midnight). An API may choose to allow the value "24:00:00" for scenarios like business closing time.



Optional. Minutes of hour of day. Must be from 0 to 59, defaults to 0.



Optional. Seconds of minutes of the time. Must normally be from 0 to 59, defaults to 0. An API may allow the value 60 if it allows leap-seconds.



Optional. Fractions of seconds in nanoseconds. Must be from 0 to 999,999,999, defaults to 0.

Union field time_offset. Optional. Specifies either the UTC offset or the time zone of the DateTime. Choose carefully between them, considering that time zone data may change in the future (for example, a country modifies their DST start/end dates, and future DateTimes in the affected range had already been stored). If omitted, the DateTime is considered to be in local time. time_offset can be only one of the following:


UTC offset. Must be whole seconds, between -18 hours and +18 hours. For example, a UTC offset of -4:00 would be represented as { seconds: -14400 }.



Time zone.


A representation of a decimal value, such as 2.5. Clients may convert values into language-native decimal formats, such as Java's [BigDecimal][] or Python's [decimal.Decimal][].

[BigDecimal]: [decimal.Decimal]:



The decimal value, as a string.

The string representation consists of an optional sign, + (U+002B) or - (U+002D), followed by a sequence of zero or more decimal digits ("the integer"), optionally followed by a fraction, optionally followed by an exponent. An empty string should be interpreted as 0.

The fraction consists of a decimal point followed by zero or more decimal digits. The string must contain at least one digit in either the integer or the fraction. The number formed by the sign, the integer and the fraction is referred to as the significand.

The exponent consists of the character e (U+0065) or E (U+0045) followed by one or more decimal digits.

Services should normalize decimal values before storing them by:

  • Removing an explicitly-provided + sign (+2.5 -> 2.5).
  • Replacing a zero-length integer value with 0 (.5 -> 0.5).
  • Coercing the exponent character to upper-case, with explicit sign (2.5e8 -> 2.5E+8).
  • Removing an explicitly-provided zero exponent (2.5E0 -> 2.5).

Services may perform additional normalization based on its own needs and the internal decimal implementation selected, such as shifting the decimal point and exponent value together (example: 2.5E-1 <-> 0.25). Additionally, services may preserve trailing zeroes in the fraction to indicate increased precision, but are not required to do so.

Note that only the . character is supported to divide the integer and the fraction; , should not be supported regardless of locale. Additionally, thousand separators should not be supported. If a service does support them, values must be normalized.

The ENBF grammar is:

DecimalString =
  '' | [Sign] Significand [Exponent];

Sign = '+' | '-';

Significand =
  Digits ['.'] [Digits] | [Digits] '.' Digits;

Exponent = ('e' | 'E') [Sign] Digits;

Digits = { '0' | '1' | '2' | '3' | '4' | '5' | '6' | '7' | '8' | '9' };

Services should clearly document the range of supported values, the maximum supported precision (total number of digits), and, if applicable, the scale (number of digits after the decimal point), as well as how it behaves when receiving out-of-bounds values.

Services may choose to accept values passed as input even when the value has a higher precision or scale than the service supports, and should round the value to fit the supported scale. Alternatively, the service may error with 400 Bad Request (INVALID_ARGUMENT in gRPC) if precision would be lost.

Services should error with 400 Bad Request (INVALID_ARGUMENT in gRPC) if the service receives a value outside of the supported range.


Represents an amount of money with its currency type.



The three-letter currency code defined in ISO 4217.



The whole units of the amount. For example if currencyCode is "USD", then 1 unit is one US dollar.



Number of nano (10^-9) units of the amount. The value must be between -999,999,999 and +999,999,999 inclusive. If units is positive, nanos must be positive or zero. If units is zero, nanos can be positive, zero, or negative. If units is negative, nanos must be negative or zero. For example $-1.75 is represented as units=-1 and nanos=-750,000,000.


Represents a postal address, e.g. for postal delivery or payments addresses. Given a postal address, a postal service can deliver items to a premise, P.O. Box or similar. It is not intended to model geographical locations (roads, towns, mountains).

In typical usage an address would be created via user input or from importing existing data, depending on the type of process.

Advice on address input / editing: - Use an internationalization-ready address widget such as - Users should not be presented with UI elements for input or editing of fields outside countries where that field is used.

For more guidance on how to use this schema, please see:



The schema revision of the PostalAddress. This must be set to 0, which is the latest revision.

All new revisions must be backward compatible with old revisions.



Required. CLDR region code of the country/region of the address. This is never inferred and it is up to the user to ensure the value is correct. See and for details. Example: "CH" for Switzerland.



Optional. BCP-47 language code of the contents of this address (if known). This is often the UI language of the input form or is expected to match one of the languages used in the address' country/region, or their transliterated equivalents. This can affect formatting in certain countries, but is not critical to the correctness of the data and will never affect any validation or other non-formatting related operations.

If this value is not known, it should be omitted (rather than specifying a possibly incorrect default).

Examples: "zh-Hant", "ja", "ja-Latn", "en".



Optional. Postal code of the address. Not all countries use or require postal codes to be present, but where they are used, they may trigger additional validation with other parts of the address (e.g. state/zip validation in the U.S.A.).



Optional. Additional, country-specific, sorting code. This is not used in most regions. Where it is used, the value is either a string like "CEDEX", optionally followed by a number (e.g. "CEDEX 7"), or just a number alone, representing the "sector code" (Jamaica), "delivery area indicator" (Malawi) or "post office indicator" (e.g. Côte d'Ivoire).



Optional. Highest administrative subdivision which is used for postal addresses of a country or region. For example, this can be a state, a province, an oblast, or a prefecture. Specifically, for Spain this is the province and not the autonomous community (e.g. "Barcelona" and not "Catalonia"). Many countries don't use an administrative area in postal addresses. E.g. in Switzerland this should be left unpopulated.



Optional. Generally refers to the city/town portion of the address. Examples: US city, IT comune, UK post town. In regions of the world where localities are not well defined or do not fit into this structure well, leave locality empty and use address_lines.



Optional. Sublocality of the address. For example, this can be neighborhoods, boroughs, districts.



Unstructured address lines describing the lower levels of an address.

Because values in address_lines do not have type information and may sometimes contain multiple values in a single field (e.g. "Austin, TX"), it is important that the line order is clear. The order of address lines should be "envelope order" for the country/region of the address. In places where this can vary (e.g. Japan), address_language is used to make it explicit (e.g. "ja" for large-to-small ordering and "ja-Latn" or "en" for small-to-large). This way, the most specific line of an address can be selected based on the language.

The minimum permitted structural representation of an address consists of a region_code with all remaining information placed in the address_lines. It would be possible to format such an address very approximately without geocoding, but no semantic reasoning could be made about any of the address components until it was at least partially resolved.

Creating an address only containing a region_code and address_lines, and then geocoding is the recommended way to handle completely unstructured addresses (as opposed to guessing which parts of the address should be localities or administrative areas).



Optional. The recipient at the address. This field may, under certain circumstances, contain multiline information. For example, it might contain "care of" information.



Optional. The name of the organization at the address.


Represents a time zone from the IANA Time Zone Database.



IANA Time Zone Database time zone, e.g. "America/New_York".



Optional. IANA Time Zone Database version number, e.g. "2019a".
