World Yoga Day

[Mokshda]

Namaste everyone
I have just learnt that the 21st of January is celebrated as world yoga day.
On a website I found that the 1st of November is celebrated as yoga day in some parts of India as this day is also known as Patanjali Jayanti.
Would anyone please throw some light and also how come this date has been decided. Is there a world regulating body that has assigned this or that day?
S.O.S. I am confused.
Thanks in advance for your reply

I found this link for anyone interested www.worldyogday.net

"On Sunday the 21st of January 2007, yoga teachers and schools around the world will donate their time and space to a two hour yoga session which is devoted to human rights.

The class should be held from 11AM - 1PM sharp, local time in each time zone, which will lead to a 24 hour yoga marathon around the world. Devoting our thoughts and energy globally to the human rights issue will generate a powerful impact.

Students attending the event will donate whatever tuition they can afford. All contributions are welcome and also students who can't pay at all – the money is important to help victims of human right violation but so is the spirit.

We love to see yogis from all styles participate in this wonderful event whether Iyengar, Bikram, Anusara, Ashtanga, Laughter Yoga…at the heart of any yoga style stands the union. Bringing all yogis worldwide together to devote their practice to this important cause will be a wonderful, spirited celebration of yoga.

Our aim is that as many nations as possible come together on this project, especially countries where human rights violation is a more dominant issue."
