Vietnamese Lunar Calendar Converter — Zodiac & Tết

Find the Vietnamese lunar year for any Gregorian date. The result shows the Vietnamese zodiac animal name (Tý, Sửu, Dần …), the date of Tết Nguyên Đán (Vietnamese Lunar New Year) and the approximate lunar month. Furthermore, the Vietnamese zodiac has one unique difference from the Chinese — it uses the Cat (Mão) instead of the Rabbit in the 4th position. This makes the Vietnamese Year of the Cat the same year other cultures call the Year of the Rabbit.

How to use the Vietnamese Lunar Calendar Converter

1
Select any Gregorian date
Click the date field and choose any date. Furthermore, the tool defaults to today — showing the current Vietnamese lunar zodiac year and Tết date immediately.
2
Read the Vietnamese zodiac animal
The result shows the zodiac animal icon, its English equivalent and its Vietnamese name. Furthermore, note that the 4th position is Mão (Cat) in the Vietnamese calendar — corresponding to the year other calendars call the Year of the Rabbit.
3
Check the Tết date
The table shows the Tết Nguyên Đán date for the current cycle. Furthermore, Tết is Vietnam's most important national holiday — a multi-day celebration of the lunar new year involving family reunions, ancestor worship and traditional foods such as bánh chưng (square sticky rice cake).
4
Understand the Cat versus Rabbit
The Vietnamese zodiac uses the Cat (Mão) in the 4th position instead of the Rabbit used in the Chinese, Korean and Japanese zodiacs. Furthermore, this is unique among major East and Southeast Asian zodiac traditions. The Cat year in Vietnam is the same year as the Rabbit year in China and Japan.
5
Note the lunar month estimate
The lunar month is estimated from days since Tết. Furthermore, for precise Vietnamese traditional almanac calculations — including auspicious dates for weddings, house moves and business openings — consult a Vietnamese Lịch Vạn Niên (perpetual calendar) or traditional astrologer.

The Vietnamese zodiac — 12 animals with Vietnamese names

The Vietnamese zodiac (Can Chi) uses the same 12-year cycle as the Chinese zodiac but with Vietnamese names. Furthermore, the key difference is that position 4 — the Rabbit in Chinese — is replaced by the Cat (Mão) in Vietnamese. The reason for this substitution is debated: one theory suggests that the Vietnamese word for Rabbit sounded like "Mão" which also means Cat in Vietnamese.

How the Vietnamese lunar calendar works

The Vietnamese lunar calendar follows the same astronomical cycles as the Chinese calendar. Furthermore, Tết Nguyên Đán falls on the same day as Chinese New Year — the second new moon after the winter solstice. The 12-year zodiac cycle uses Vietnamese names but identical timing to the Chinese cycle.

Vietnamese zodiac = same cycle as Chinese (different animal names)
Tết = same astronomical day as Chinese New Year each year
Position 4 = Mão (Cat) instead of Rabbit
Year change = occurs on Tết, not 1 January
Lịch Vạn Niên = Vietnamese perpetual almanac for precise dates

Worked example: Year of the Cat 2023

In 2023, China celebrated the Year of the Rabbit. Vietnam celebrated the same year as the Year of the Cat (Mão). Tết 2023 fell on 22 January 2023.

VietnameseCat 🐈Năm Quý Mão — Year of the Cat
KoreanRabbit (토끼)토끼해 (Year of the Rabbit)
JapaneseRabbit (卯)卯年 (Year of the Rabbit/Hare)
The Vietnamese Cat year is unique among the world's major zodiac traditions — all other East and Southeast Asian zodiacs use the Rabbit in this position. Furthermore, this makes Vietnamese zodiac merchandise and birthday celebrations for "Mão" years distinctly cat-themed, rather than rabbit-themed.

What is the Vietnamese lunar calendar?

The Vietnamese lunar calendar (Âm Lịch) follows the same astronomical principles as the Chinese calendar. Furthermore, it governs Tết, Tết Trung Thu and traditional ancestral observances. The calendar uses the same month-length system as the Chinese calendar — alternating 29 and 30-day months with occasional 13th intercalary months.

Vietnam uses the Gregorian calendar for civil purposes. Furthermore, the lunar calendar governs traditional and religious observances. Most families consult the lunar calendar for ancestor memorial days, festivals and auspicious date selection. Moreover, the Lịch Vạn Niên (perpetual almanac) is widely consulted for these calculations.

Tết — the Vietnamese New Year

Tết Nguyên Đán is Vietnam's most important national holiday. Furthermore, it is a multi-day celebration involving family reunions, ancestor worship and traditional foods. Families clean homes, buy flowers and prepare traditional foods for the celebration. Furthermore, peach blossoms decorate northern homes while yellow apricot blossoms are used in the south. Moreover, Tết celebrations span the first 15 lunar days — the official holiday covers the first 5.

Why the Vietnamese lunar calendar matters

Vietnam is a major Southeast Asian economy and manufacturing hub. Furthermore, Tết is the longest national holiday period — significantly reducing business activity for weeks. Supply chain teams must plan ahead — production and shipping capacity drops significantly before and after Tết. Moreover, Tết dates shift each year with the lunar calendar, requiring annual planning updates.

The Vietnamese diaspora — over 5 million people in the US, Australia and France — celebrates Tết globally. Furthermore, community events and restaurant bookings revolve around the Tết calendar. Moreover, knowing the Vietnamese zodiac animal helps craft culturally appropriate New Year marketing.

The unique Cat year in Vietnamese marketing

The Vietnamese Cat year (Mão) creates distinct marketing opportunities compared to the Rabbit year in Chinese markets. Furthermore, Vietnamese New Year (Tết) products in Cat years feature cat imagery rather than rabbit imagery — while simultaneously, Chinese New Year products for the same year feature rabbits. Moreover, brands serving both Vietnamese and Chinese consumer segments must produce different creative for the same lunar year when it is a Cat/Rabbit year.

Frequently asked questions

The Cat (Mão) appears in position 4 of the Vietnamese zodiac instead of the Rabbit used by the Chinese, Korean and Japanese zodiacs. Furthermore, several explanations have been proposed — the most cited is that the Sino-Vietnamese word for Rabbit (Mão) sounds identical to the Vietnamese word for Cat. Another theory suggests that cats were more familiar than rabbits in early Vietnamese agricultural communities. Moreover, this substitution is unique to Vietnam among the world's major zodiac traditions.
Tết Nguyên Đán 2026 falls on 17 February 2026 — the same day as Chinese New Year. Furthermore, 2026 is the Year of the Horse (Ngọ, Ngựa) in the Vietnamese calendar. The official Tết public holiday in Vietnam runs from approximately 15–19 February 2026 (the exact days are announced annually by the Vietnamese government). Moreover, businesses in Vietnam typically operate at reduced capacity for two to three weeks around Tết.
The Lịch Vạn Niên (literally "ten-thousand-year calendar") is the Vietnamese perpetual almanac — a comprehensive reference for traditional calendar calculations. Furthermore, it includes lunar-solar conversions, auspicious and inauspicious dates, zodiac information and traditional fortune calculations. Moreover, it is widely used by Vietnamese families for planning weddings, house moves, business openings and ancestral memorial days — occasions where the lunar calendar date is considered highly significant.
The official Vietnamese government public holiday for Tết is typically 5 to 7 days — covering the eve and the first 5 days of the first lunar month. Furthermore, in practice, many workers take additional leave, and businesses often operate at reduced capacity for 2 to 3 weeks.

Yes. Tết Trung Thu falls on the 15th day of the 8th lunar month — the same date as the Chinese Mid-Autumn Festival and the Korean Chuseok, all corresponding to the same full moon.
