This site basically tells you the day of the week that you were born on. It also tells you other pointless but fun things such as: your star sign, how old you are, what season you were born in, how long until your next birthday, and how many days/hours/seconds you have been alive (assuming 12:00 midnight so the last two are approximations only). The site also provides links to other websites, so you can find more information such as famous people or events that share your birthday.
Disclaimer: Although every effort has been made to ensure that the information calculated is accurate, dayofbirth.co.uk cannot be held responsible for any errors that occur.
