public class DateDt
extends BaseDateTimeDt

Represents a FHIR date datatype. Valid precisions values for this type are:

• TemporalPrecisionEnum.YEAR
• TemporalPrecisionEnum.MONTH
• TemporalPrecisionEnum.DAY

Note on using Java Date objects: This type stores the date as a Java Date. Note that the Java Date has more precision (millisecond precision), and does not store a timezone. As such, it could potentially cause issues. For example, if a Date contains the number of milliseconds at midnight in a timezone across the date line from your location, it might refer to a different date than intended.

As such, it is recommended to use the Calendar or int,int,int constructors

DateDt

public DateDt()

Constructor

DateDt

public DateDt(Calendar theCalendar)

Constructor which accepts a date value and uses the DEFAULT_PRECISION for this type.

DateDt

public DateDt(Date theDate)

Constructor which accepts a date value and uses the DEFAULT_PRECISION for this type. Please see the note on timezones on the class documentation for considerations when using this constructor!

DateDt

public DateDt(Date theDate,
