Fryderyk Chopin was born in Żelazowa Wola, 46 kilometres (29 miles) west of Warsaw, in what was then the Duchy of Warsaw, a Polish state established by Napoleon. The parish baptismal record gives his birthday as 22 February 1810, and cites his given names in the Latin form Fridericus Franciscus (in Polish, he was Fryderyk Franciszek). However, the composer and his family used the birthdate 1 March,[n 2] which is now generally accepted as the correct date.

Answer this question, if possible (if impossible, reply "unanswerable"): On what date was Frédéric born on?
22 February 1810
