Vietnamese calendars & memorable dates
This calendar pairs Gregorian dates with lunar days, months, and years, including leap months. Select a date for details, use the arrows to browse, or choose a month and year. Lunar conversions use UTC+7 consistently for 1900–2100 and do not reconstruct historical time zone changes.
Lunar festivals such as Tết Nguyên đán, the Hùng Kings Commemoration, Tết Đoan ngọ, Vu Lan, and the Mid-Autumn Festival are converted to Gregorian dates for your selected year. The monthly calendar also includes Vietnamese occasions such as Reunification Day on April 30, National Day on September 2, Women’s Day on October 20, and Teachers’ Day on November 20.
The international category includes observances recognized by the United Nations, UNESCO, and WHO. It excludes national days and traditional festivals of other countries. Globally recognized remembrance and awareness days remain international even when named for a place. Observance weeks, event schedules, and individual language and culture days are outside this list.
Choose a conversion direction and enter a date. When converting a lunar date, select Leap month only for a leap month in that year. Invalid dates, such as day 30 in a 29-day lunar month, produce an error instead of silently changing to another date.
International observance list reviewed: Oct 13, 2026. These are recurring annual observances, not a record of events held in every historical year. New observances may be added as publishing organizations update their lists.
