Swiss writer Victor Duret [de] stated that Elizaveta was born according to the Russian calendar on 17 September 1799.[3] Russian academic Ksenia Andreevna Sozinova reviewed letters written by the couple and stated Elizaveta was born on 5 September 1799,[4] which is confirmed by Speransky's biographer, Modest Andreyevich Korff [ru].[5] Conversion of that date would be one day prior to the date given by Duret,[6] because when he wrote in 1867 a twelve-day difference existed, but by the twentieth century, an eleven-day conversion factor was used.[7] Austria changed from the Julian calendar to the Gregorian calendar in 1583.[8] Russia did not change from the Julian calendar until February 1918.[9] To avoid confusion all dates are given in New Style, or Gregorian format, unless noted otherwise.
