Holi is a spring festival in Nepal and India, also known as the festival of colours or the festival of sharing love. Holi is a two day festival which starts on the Purnima (Full Moon day) falling in the Bikram Sambat Hindu Calendar month of Falgun which falls somewhere between end of February and Mid of March in the Gregorian Calendar. The first day is known as Holika Dahan or Chhoti Holi while the second day is known as Rangwali Holi, Dhuleti, Dhulandi or Dhulivandan.
Holi is celebrated at the approach of the vernal equinox on the Phalguna Purnima (Full Moon). The festival date varies every year, per the Hindu calendar, and typically comes in March, sometimes February in the Gregorian Calendar. The festival signifies the victory of good over evil, the arrival of spring, end of winter, and for many a festive day to meet others, play and laugh, forget and forgive, and repair broken relationships, and is also celebrated as a thanksgiving for a good harvest
