We don’t know who Satoshi is and we seemingly by no means will, however the pseudonymous founder does apparently have a birthday. Satoshi entered a start date once they registered the pseudonym with The P2P Basis. Satoshi’s birthday is, in line with that registration, April 5, 1975. (For proof, Satoshi’s age confirmed up as 38 on The P2P Basis on April 4, 2014, and as 40 on April 5, 2015, implying an April 5, 1975, birthday.)
