The Rigpa Calendar has this as the lunar 1st of the third Tibetan month: the Kalachakra New Year. We have this as the lunar 2nd, Bird, Khen, Black 2. Confusing? Yes, it is, but tomorrow it all comes together: Rigpa has it as the lunar 3rd and so do we.
Anyway, today is not bad for prayer flags. If you have something important to do, today is the day.
