# Valid Date and DateTime Formats

Specify the right format for `dateTime` and `date` fields.

## dateTime

Use the yyyy-MM-ddTHH\:mm:ss.SSS+/-HH:mm or yyyy-MM-ddTHH\:mm:ss.SSSZ formats to specify `dateTime` fields.

- `yyyy` is the four-digit year
- `MM` is the two-digit month (01-12)
- `dd` is the two-digit day (01-31)
- 'T' is a separator indicating that time-of-day follows
- `HH` is the two-digit hour (00-23)
- `mm` is the two-digit minute (00-59)
- `ss` is the two-digit seconds (00-59)
- `SSS` is the optional three-digit milliseconds (000-999)
- `+/-HH:mm` is the Zulu (UTC) time zone offset
- 'Z' is the reference UTC timezone

When a timezone is added to a UTC `dateTime`, the result is the date and time in that timezone. For example, 2002-10-10T12:00:00+05:00 is 2002-10-10T07:00:00Z and 2002-10-10T00:00:00+05:00 is 2002-10-09T19:00:00Z. See [W3C XML Schema Part 2: DateTime Datatype](http://www.w3.org/TR/xmlschema-2/#dateTime).

## date

Use the yyyy-MM-dd format to specify `date` fields.

:::note
Specifying an offset for `date` is not supported.
