Tihar, also known as Diwali or Deepawali or the festival of lights, is a festival celebrated by Hinduism, Jainism, and Sikhism, for driving away darkness with light and defeating evil with goodness. Later, it's also regarded as a celebration of "inner light" and some Buddhists also celebrate this festival.

Tihar celebrates for five days starting from August 15th in the Nepalese calendar(late October or early November in the Gregorian calendar) every year, that is the 15th full moon day in the eighth month of the Hindu calendar.

In Nepal, Tihar is held in high regard, only second to the Dashain. It's is also known as the most beautiful festival. In some parts of India, it even replaced Dashain as the largest festival. Nepali Tihar falls on November 13th and lasts until the 17th in 2020.
