Is today/was yesterday Shan New Year?

ayyyy, just your usual ignorant foreigner here... just curious, is/was November 30 the Shan/Tai Yai new year?

I saw celebrations posted on some Shan-Ni outlets (https://www.facebook.com/photo?fbid=1039034538234563&set=a.681589937312360&locale=ja_JP) and thought it may be a Shan-Ni specific event, but googled a bit more and found a few articles mentioning today as the Shan / Tai Yai New Year (this year).

Didn't see much in terms of celebrations/announcements from any of the other Shan-based people/pages/groups I follow though.

assuming that is correct, happy new year! 🎉
