Frequently asked questions
Is the Vietnamese lunar calendar the same as the Chinese one?
Almost always, but not every year. Both use the same astronomical rules, but Vietnam computes them for UTC+7 and China for UTC+8, so when a new moon falls near midnight the months can start a day apart — Tết was on 17 February 2007 in Vietnam but 18 February in China.
What is Can Chi?
A 60-name cycle combining 10 heavenly stems and 12 earthly branches, used to name lunar years, months, days and hours. 2027, for example, is Đinh Mùi — a Year of the Goat.
Why does the Vietnamese zodiac have a Cat and a Buffalo?
In Vietnam the branch Mão is the Cat (not the Rabbit) and Sửu is the Buffalo (not the Ox). The years are otherwise the same as the Chinese zodiac.
What is a leap month?
About every three years the lunar calendar adds a 13th month to stay in step with the seasons. The leap month repeats the number of the month before it, for example a second “month 6” in 2025.
