Holi



Holi ( /ˈhoʊliː/; Sanskrit: होली Holī) is an ancient Hindu spring festival, originating from the Indian subcontinent. It is celebrated predominantly in Pakistan, India and Nepal, but has also spread to other areas of Asia and parts of the Western world through the diaspora from the Indian subcontinent. Holi is popularly known as the Indian "festival of spring", the "festival of colours", or the "festival of love". The festival signifies the arrival of spring, the end of winter, the blossoming of love, and for many a festive day to meet others, play and laugh, forget and forgive, and repair broken relationships. The festival also celebrates the beginning of a good spring harvest season. It lasts for a night and a day, starting on the evening of the Purnima (Full Moon day) falling in the Vikram Samvat Hindu Calendar month of Phalgun, which falls somewhere between the end of February and the middle of March in the Gregorian calendar. The first evening is known as Holika Dahan (burning of demon holika) or Chhoti Holi and the following day as Holi, Rangwali Holi, Dhuleti, Dhulandi, or Phagwah.

Desi Arnaz



Desi Arnaz

Desiderio Alberto Arnaz y de Acha III (March 2, 1917 – December 2, 1986), better known as Desi Arnaz or Desi Arnaz, Sr., was a Cuban-born American actor, musician, and television producer. He is best remembered for his role as Ricky Ricardo on the American television series sitcom I Love Lucy. He co-starred on that show with dramatic and comedic actress Lucille Ball (1911-1989), to whom he was married at the time. He and Ball are generally credited as the inventors of the syndicated rerun, which they pioneered with the I Love Lucy series.

Arnaz and Lucille Ball co-founded and ran the television production company Desilu Productions, originally to market I Love Lucy to television networks. After I Love Lucy ended, Arnaz went on to produce several other television series, at first with Desilu Productions, and later independently; examples of which included The Ann Sothern Show and The Untouchables. He was also renowned for leading his Latin music band, the Desi Arnaz Orchestra.
