Vietnam's Lunar Calendar Marks July 30‑31, 2026 as Inauspicious Days

According to the Vietnamese lunar calendar, Thursday 30 July 2026 (Gregorian) corresponds to the 17th day of the 6th lunar month, a Chu Tước day traditionally regarded as unlucky for major undertakings such as travel, construction or weddings. The same date is also observed internationally as the United Nations' World Day Against Trafficking in Persons and the International Day of Friendship.

Friday 31 July 2026 aligns with the 18th day of the 6th lunar month and is classified under the Thiên Lao Hắc Đạo (black‑direction) influence, indicating conflict and lack of benefit for large projects. The calendar lists specific auspicious hours for activities like legal matters, meetings with elders, and paperwork, while advising against construction, house‑moving, weddings, and opening new businesses during the day.
