MEHREGAN is the Autumnal Equinox just like Now Rooz is the Vernal Equinox.

In ancient times Mehregan like Nou Rooz was celebrated exactly at the moment of the Autumnal Equinox which falls on the 1st of the month of Mehr which corresponds to 23 September. The celebrations lasted for 10 days and ended on Mehr Day in Mehr month when the name of the Month and the name of the Day were the same.

After the genocide committed against our ancestors we lost all the science and knowledge and in modern times we just celebrate the last day of the festival, the 10th day.
