This international observance happens each November 13 since 1998 under the auspices of the World Kindness Movement which is a coalition of nations.
It is observed in a multitude of countries and that participation is increasing over the years in support of the quality of being friendly, generous, and considerate.
In my existence I can think of much less worthwhile pursuits. Love is kind.
1 Corinthians 13:4-8
4
Charity suffereth long, and is kind; charity envieth not; charity vaunteth not itself, is not puffed up,
5
Doth not behave itself unseemly, seeketh not her own, is not easily provoked, thinketh no evil;
6
Rejoiceth not in iniquity, but rejoiceth in the truth;
7
Beareth all things, believeth all things, hopeth all things, endureth all things.
8
Charity never faileth: but whether there be prophecies, they shall fail; whether there be tongues, they shall cease; whether there be knowledge, it shall vanish away.
