Business Days in December 2029 for Vietnam

December 2029 has 21 working days under the Vietnamese national holiday calendar. The month spans 31 calendar days, of which 10 fall on a weekend and 0 are Vietnamese national holidays that lands on a weekday. The remaining 21 weekdays are countable as working days for invoicing, deadline tracking, and contract math.

December 2029 contains no Vietnamese national holidays that fall on a weekday. Banks, the central clearing system, and Vietnam financial markets keep their normal schedule throughout the month under this calculator's national-only holiday set.

Tet (Lunar New Year) is Vietnam's longest national closure, gazetted by the Government annually under Article 112 of the Labour Code 2019. The official statutory closure is 5 days but the Government typically pulls in adjacent weekends to create a 7-9 day national holiday, sometimes longer. Make-up working Saturdays after Tet are gazetted to balance the calendar year. Banks, the HOSE and HNX stock exchanges, and government offices all close. This calculator uses the most-commonly observed 7-9 day window based on the prior year's gazette where the next year's notice has not been published.

Hung Kings Commemoration Day (Giỗ Tổ Hùng Vương) falls on the 10th day of the 3rd lunar month and honours the legendary founders of Vietnam. The Gregorian date varies each year, typically in early to mid-April. It became a national public holiday in 2007 and closes banks, the HOSE/HNX, and government offices. When the lunar date falls on a weekend, the Government may declare an in-lieu Monday by decree but this is not automatic.

Two things shift the monthly count for Vietnam. First, the day of the week the first of the month lands on changes the count of each weekday. Second, Vietnamese national holidays anchored to a fixed date shift their weekday across years. Some years a fixed-date holiday lands on a weekend; some countries shift the observance to an adjacent weekday and some absorb it into the weekend. December 2028 also had 21 working days, so the working capacity is unchanged year over year.
