UN declares International Happiness Day THE UN has declared March 20 the International Day of Happiness - and it wants everyone to join in the fun. The UN General Assembly passed a resolution proclaiming the new commemoration that adds to an already packed UN calendar of international days - from world poetry day to world migratory bird day. "The pursuit of happiness is a fundamental human goal," said the resolution, which was passed by consensus in the 193-member assembly today. The resolution calls on all member states "to observe the International Day of Happiness in an appropriate manner, including through education and public awareness activities." Securing happiness day was part of a diplomatic campaign by the Himalayan kingdom of Bhutan, which has its own gross national happiness index. Many governments now say new elements, including happiness, must be included in ways of measuring prosperity dominated by economic indicators.
