World No-Tobacco Day: May 31

May 31st is World No-Tobacco Day.

This anniversary was set to commemorate the 40th anniversary of World Health Organization (WHO).

The World Health Organization was founded on April 7, 1948, so April 7 was set as the anniversary at first.

But in 1988, it was changed onto May 31.
