Ever since1923, on 8 January, a tradition takes place in Nea Petra called Babo or Vrexoudia. According to this tradition, women take over the village and force the men to do the home chores. During the Vrexoudia tradition on the same day, women actively provoke water fights with the men of the village. The 8th of January is also called the day of Gynecocracy in Nea Petra due to this tradition.
