This page describes a set of tests included in version 1.05 of the GEDCOM file assess.ged (download - view). Details change between versions.

Area Summary

People with the surname "Date Valid" have birth events with valid GEDCOM dates. GEDCOM dates include full dates, partial dates, approximate dates, calculated dates, date ranges, and date periods.

The keywords that modify a date are short, uppercase values like "ABT" and "FROM", but they may be rendered differently by the target application.

If the target application does not support one of the date formats used in your data, you should (1) adjust the date value before exporting or (2) adjust the value after importing. Use a date value that best approximates the original, unsupported value.

Of the date values tested in this area, the most common problem dates are:

Some target applications make it difficult to identify unsupported dates because they show the text value of the imported date even when the application was unable to parse the date. One clue is to look somewhere in the user interface where lifespans appear. If there is no birth date for the person, the date was probably not recognized. That is one reason why the tests use Birth events.

Another way to detect unsupported dates is to compare the rendering of the date to other date values. Many programs have options for formatting dates (full months, abbreviated months, zero-filled day numbers, etc.) and an unsupported date will not reflect the formatting options. For example, if the target application usually shows dates using a full month name, but a test shows an abbreviated month name, it's likely that the target application does not support the date value used in the test.
