Ngenpa Gudzom (Dzongkha: ངན་པ་དགུ་འཛོམས; Wylie: ngen pa gu 'dzoms which literally means (Ngenpa = Evil, Gu = Nine, Dzom = Meet)), also known as "The Meeting of Nine Evils" is one of the festivals in the Bhutan usually observed on the 7th day of the 11th month of Bhutanese Calendar,[1][2][3][4] although the traditional astrological period of Ngyenpa Guzom begins sometime during the afternoon of the 6th day.

Some people argue that, unless Ngyenpa Guzom is reinstated as a public holiday, the importance of the day will be forgotten and that the future generations will have no idea about this tradition.

[3] Ngenpa Guzom falls on the day with the longest night of the year based on the lunar calendrical calculation and geomancy.

On this inauspicious day, some activities like erecting new monuments, consecrating, pacifying local deities, reciting religious texts, learning, transferring and taking over properties, preaching, appointing new positions, moving, starting a new business, getting married, celebrating, travelling long distances, and selling land are discouraged.

[1][4] Usually, Nyenpa Guzom is observed in the eastern part of Bhutan as a festival among the family members to eat, drink and play traditional games like archery, dego and khuru.
