HL7® Definition

Choose any HL7® trigger event, segment, data type or table to get its definition:

- or -

DT: Date

In prior versions of HL7, this data type was always specified to be in the format YYYYMMDD. In the current and future versions, the precision of a date may be expressed by limiting the number of digits used with the format specification YYYY[MM[DD]]. Thus, YYYY is used to specify a precision of year, YYYYMM specifies a precision of month, and YYYYMMDD specifies a precision of day.
