Marked on the 10th day of the 3rd month on the lunar calendar, every year, Zhabdrung Kuchoe (the death anniversary of Zhabdrung Ngawang Namgyal ) is one of the most important days for Bhutanese. 

On arrival to Bhutan from Tibet in 1616, Zhabdrung unified the regions of the country together and named 'Druk'. Thus, he is referred to as the founder of Druk, Bhutan. In 1651, he passed away. To pay homage and respect to the FOUNDER, Bhutanese mark the day of Zhabdrung Kuchoe every year.
