Facebook's Gross National Happiness is a chart that shows you the days of the year that people are most happy!
It is a Facebook application presented as a graph that will track people's status updates by counting whether the update is positive or negative. This would include, amongst others, such words as 'happy', 'yay', 'awesome' and unhappy words include 'sad', 'doubt' and 'tragic'.
The Gross National Happy Index was launched in October 2009 but has recently included the UK.
The happiest days are Christmas, New Year and Valentine's Day and Fridays, Saturdays and Sundays.
