May 17th of the solar calendar (April 1st of the Binh Ngo year) is Tan Mao day, Quy Ty month, belonging to Huyen Vu Hac Dao.
According to the ten thousand-year calendar, this day has Thien Can (Heaven Can) encroaching on Dia Chi (Death Branch), so it is assessed as not favorable for important tasks. If carrying out major tasks, it is easy to generate obstacles, waste time and effort, but the results are not as desired. Therefore, many important activities are recommended to be restricted from being performed during the day.
According to the book "Lịch âm - dương Cát Tường 2026" (Hong Duc Publishing House), May 17th is in the Lập Hạ tiết khí. The zodiac signs compatible with the day include Tuất, Mùi and Hợi, while the zodiac signs Quý Dậu, Kỷ Dậu, Ất Sửu and Ất Mùi need to be more careful when resolving important tasks.
Although it is not a good day, there are still some suitable zodiac hours to handle necessary work such as Ngo hour (11am-1pm) and Dau hour (5pm-7pm) meaning smooth traffic, easy to encounter favorable conditions.
Regarding departure, this is Tang Feng day, which is considered quite good if moving to seek wealth or find job opportunities. The Southwest direction is a suitable direction to welcome the God of Joy and the God of Wealth, while the main North direction should be avoided due to encountering the Black God.
This day is suitable for construction and repair work. Conversely, many other important things are recommended not to be carried out such as burials, weddings, openings, long trips, building doors or placing beds.
