Auspicious days by your age: a whole-year calendar

Enter your lunar birth year, choose an activity and the year to view. The tool colours every day of all 12 months using Hoàng đạo, day officer, taboo days and clash/harmony with your age. Everything runs in your browser.

If you were born before Tết, use the previous year (born 15 Jan 2000 → 1999).

Results come from our own rule table, which has not been reviewed by an expert; books score differently. For cultural reference only, not advice. Tap a day for details.
