Some common taboo days
This day is not a Tam nương, Nguyệt kỵ or Dương công kỵ day. Only these three are checked; other taboo days (Sát chủ, Thọ tử, Vãng vong, Nguyệt phá…) are not, so this does not mean the day has no taboo at all.
Suitability by activity (for reference)
Scores come from our own rule table (Hoàng đạo/Hắc đạo, day officer, taboo days), have not been reviewed by an expert and do not include your age. Almanacs score differently; use the day finder to add your birth year.
