Field notes
The page asks for a birth date, counts the elapsed days, then projects that same interval backward to a “mirror date”; it says the matching person was the user’s age on their birth date. The result shifts back one day each day. BirthMirror says the entered date stays in the browser, while its people data comes from Wikidata and its credited photos from Wikimedia Commons.
