Vietnam marks July 12 and 13, 2026 lunar calendar days with cultural and historic significance

On 12 July 2026 the Vietnamese lunar calendar records the day Đinh Hợi, which traditional belief regards as auspicious for travel and major undertakings. The date also commemorates the 80th anniversary of Vietnam’s People’s Public Security force, founded on 12 July 1946, highlighting its long‑standing role in national stability.

The following day, 13 July 2026, is the lunar day Mậu Tý, noted in folk tradition as inauspicious for new ventures and associated with the end of the Giáp Ngọ month. Historically, 13 July 1885 saw Emperor Hàm Nghi issue the Cần Vương edict calling for resistance against French colonial rule. Western sources also note that 13 July is observed as “National Rock Day” in the United States, but the Vietnamese focus remains on the calendar’s cultural meanings.
