Go to the link http://www.poisklyudei.ru/search.php. Here you can find a person on many parameters, including date of birth.
Spend search independently. You can start with an easy one. Go to the social network. Sign up on the website "Odnoklassniki", "Vkontakte", "circle of friends", "My world". To find a person by date of birth, you must enter this information into the address bar of a search query. If you know the name and surname, place of residence, be sure to include them. This significantly narrows the geography of search.
Do not despair if this search has not given results, as the cause of the failures can be several. For example, the user is not registered on the web site. Maybe he came up with a fictitious name or date of birth. Thus, the distorted information will affect the required query.
