Today is lunar 29, Horse, Li, White 8. I wouldn't hang prayer flags today. Today is a good day for sang. Avoid contact with unclean things today: garbage, blood, etc. The 29th is of course a Dharmapala day, but this month, the Rigpa Calendar has that pegged for tomorrow (Friday the 24th April), because of the double day mentioned earlier this week. Therefore, the 28th that arises today (according to one system of calculation, as published in the Rigpa Calendar because of the double day) is a baden, or very bad day for raising prayer flags. Confused yet? Note that the calendar used by Rigpa is the same as the Men-Tsee-Khang Calendar, which is to be regarded as authoritative in some senses; however, the calendar I am using, which is the combined Chinese and Kalachakra calendar, is no less authoritative, so who ya gonna' call?
