This example demonstrates how a birth or deceased date with unknown day, estimated month and accurate year would be represented.

Note that "2004-06-00" is NOT a valid FHIR date.

Details include:

• A valid FHIR date example for birth date and deceased date is "2004-06-08” but not "2004-06-00".
• A date accuracy indicator of "UEA" indicates that the day is unknown but month is an estimate and year is accurate.
• When a code value contains "U", the corresponding date components (individual or combination) for birth or deceased dates must be ignored.
• When a code value contains "A", the corresponding date components (individual or combination) for birth or deceased dates must be accurate.
