Why do we celebrate National High Five Day?

The high five, a well-known hand gesture of celebration and greeting, is believed to have been invented by Dusty Baker and Glenn Burke, both members of the Los Angeles Dodgers. According to National Day Calendar, the two came up with the hand gesture while they were celebrating the success of their game on Oct. 2, 1977.

Explanation:

high fives are used to greet people, express solidarity and congratulate someone for their achievement. It has become a universal hand gesture as well.

But Unfortunately, people cannot celebrate it by giving each other high fives due to the pandemic that calls for social distancing.
