Suetonius58: "On the ninth day before the Kalends of February... Ruled three years, ten months and eight days"; Cassius DioLIX.30: "Thus Gaius, after doing in three years, nine months, and twenty-eight days that has been related, learned by actual experience that he was not a god." (this seems to give 23 January, but Dio is probably using exclusive reckoning, which does give 24).[182]
