dob <date>
dob none|erase|off|delete

This sets your birth date for the finger display. Setting your date of birth to none clears this information.

Date must be in the format yyyy-mm-dd.

If you don't live in the UK, you should make sure you use the timezone command to tell the mud where you are in the world, so birthday announcements are made at the correct time.
