Diwali

Diwālī or Dīpāvali (also transliterated Deepavali; Sanskrit: row of lights) is the Hindu Festival of Lights. For Jains it is one of the most important festivals, and beginning of the Jain year. It is also a significant festival for the Sikh faith. Diwali is one of the most popular and eagerly awaited festivals of India. It is celebrated for 5 consecutive days in the Hindu month of Ashwayuja which usually corresponds to the month of October or November. Hindus, Jains and Sikhs celebrate Diwali and use the occasion to celebrate life and strengthen relationships. Celebrations focus on lights and lamps, particularly traditional diyas (as illustrated). Fireworks may also be associated with the festival in some regions.
