Chinese 10th, M-T-K 10th. Snake, Khen, Green 4. Today is Guru Rinpoche Day. However, please note that today is also nyi nak, so it a good day to stick close to home. Some people take that to mean "hide under the bed," but I don't think that is necessary. When in doubt, practice cures all ills.
Today is also Yom Kippur.
Today is a great day to get out the red food coloring, barley flour, honey, and butter, and make a nice torma for the puja at 6:00 o'clock in the evening.
