Kartik Naach, also known as Kachhalā Pyākhan, is a dance musical play performed every year during the month of Kartik (October or November) in Nepal. It was initiated in 1641 AD by the Nepali Malla King Siddhi Narsingh Malla and takes place at Kartik Dabali in Patan Durbar Square. Originally performed over two days, it has been extended to a duration ranging from two to 27 days, featuring 17 tales of the Hindu god Vishnu. King Narsingh Malla's son, Shree Niwas Malla, added seven days to the performance, and his grandson, Yog Narendra Malla, further extended it to 15 days.
