International days are very powerful to help raise awareness over an issue, event, or idea. Being internationally celebrated means the participation of dozens to hundreds of nations all across the globe.

Anyone can simply categorize all of the existing international days to for example the ‘women’, the ‘youth’, or the ‘human rights’ category. But, how about on environmental awareness and healthy lifestyle category? Are they have been covered enough? Or we need the UN to designate them more?
