At "Ai Karty" (old moon) the moon aged became wise. But at the same time quarrelsome and malicious. Before its death, the moon reigned over a totally dark night. The forces of life and death met during these nights. After the meeting they separated, only to meet again after a defined period. When the  old moon died, a new one was born, and so on, ad infinitum. The Turkic people trusted the magic influence of the Moon. He was their sole "night lantern". The celebrations of malicious spirits occurred mostly at night. The rituals and trances of witches and demons were always timed according to the phases of the Moon. In Turkish culture At night, illnesses got worse and caused more deaths. To please the Moon God, those born during a full moon were given names as such: Aisylu (Aysulu), Aituly (Aytulu), Ainir (Aynur), Aizirek (Ayzerek) and Ainaz (Aynaz).
