Possible Causes

• The most common cause is a typo in the birth date.

Action Steps

Edit the birth date by:

1. Correcting the typo based on information found in the profile.
2. If no information is found, look for a source that will have the correct birth date. Add a citation for this source to the profile.
3. If no source can be found, use a reasonable guess based on a date of death or marriage or the birth date(s) of family members. Mark the date as "Uncertain."
4. If the profile has no sources and no relatives and no reasonable guess can be made, delete the impossible birth date. {if this leaves the profile with no date, it is important to add a note in the profile regarding what was in the date field and why it was removed}

Note: All of these profiles will be private. If you are not the Profile Manager or on the Trusted List, you will need to post a message on the profile for the PM.

Technical Stuff

1. When the full date is entered the date must not be in the future, compared to the date of the most recent database dump.
2. When an incomplete date is entered all missing components (day, month) will be assumed to have value 1 for comparison purposes. So 2016 would for this purpose be assumed to be January 1, 2016. May 2016 would be assumed to be May 1, 2016.
3. The birth date in private profiles is available for validation only in decade format, i.e. date 2017-01-01 is decade 2010. In this case, all decades up to and including the current one are considered valid.
