Diwali (also spelled Devali in certain regions) or Deepavali,[note 1] popularly known as the "festival of lights," is a festival celebrated between mid-October and mid-December for different reasons. For Hindus, Diwali is one of the most important festivals of the year and is celebrated in families by performing traditional activities together in their homes. For Jains, Diwali marks the attainment of moksha or nirvana by Mahavira in 527 BCE.

In Judaism, the New Moon ushers in a new month
Rosh Chodesh or Rosh ḥodesh (Hebrew: ראש חודש; trans. Beginning of the Month; lit. Head of the Month) is the name for the first day of every month in the Hebrew calendar, marked by the appearance of the new moon. The new moon is marked by the day and hour that the new crescent is observed. It is considered a minor holiday, akin to the intermediate days of Passover and Sukkot.
