Introduction
For generations, Vietnamese people have practiced the custom of choosing auspicious dates and times (ngày lành tháng tốt) before important events like weddings, groundbreaking, or moving into a new house. This reflects a cultural desire for good luck and smooth proceedings.
It is important to note that these are popular customs for reference only. Practices vary by region and family, and no single method is the "only correct" one.
Basic Principles
Identify the Purpose
Each auspicious day is suited for specific tasks. For example, some days are good for ceremonies and offerings, while others are specifically noted for weddings or groundbreaking. Always check the day's recommended activities.
Avoid Unlucky Days
Commonly avoided days include:
- Tam Nương days
- Nguyệt Kỵ days (5th, 14th, 23rd of the lunar month)
- Other days considered highly inauspicious
Prefer Hoang Dao Days and Hours
According to traditional calendars, days are classified into 12 star positions, with 6 being Hoang Dao (auspicious) and 6 being Hac Dao (inauspicious). These are clearly marked in Vietnamese almanacs (lịch vạn niên) and apps. Similarly, each day has specific Hoang Dao hours.
For example, data from Tuổi Trẻ newspaper for April 2025 shows:
- April 9, 2025 (lunar 12/3): Kim Quy Hoang Dao day. Good hours: Ty (23:00-0:59), Suu (1:00-2:59), Thin (7:00-8:59), Ty (9:00-10:59), Mui (13:00-14:59), Tuat (19:00-20:59). Suitable for: Worship, engagement, wedding.
- April 15, 2025 (lunar 18/3): Tu Menh Hoang Dao day. Suitable for: Engagement, wedding, moving house, groundbreaking, pouring roof, opening business.
