With all the war, violence and family strife around the world, happiness is even more in demand and will play a bigger role in the mental health of people. The International Day of Happiness came into being in 2013 when the United Nations recognised this and the importance happiness plays in overall progress. Since then, 20 March has been celebrated as International Day of Happiness.
