Thimphu is a spring festival.
=== Urban expansion ===Over the last 50 years, since its establishment as the capital of Bhutan, Thimphu has witnessed expansion, initially at a slow pace, then rapidly after the country was opened up to the outside world after the coronation of the fourth King, Jigme Singye Wangchuck
 In 2008, this paved way for the transition from absolute monarchic rule to a parliamentary democratic constitutional monarchy, with Thimphu as the headquarters of the new government, with the national defined objective of achieving "Gross National Happiness" (GNH) concomitant with the growth of Gross National Product (GNP)
