Le Tet - the Vietnamese lunar new year, when the first person to cross into the new year decides the fortune of the house

Le Tet is the Vietnamese lunar new year, observed over five days with a peach tree in the corner, a pot of banh chung, and a careful rule about who crosses the door first - because the first person to enter in the new year sets the fortune of the house.

The one-line summary

Five-day Vietnamese lunar new year, late January to mid-February. Cultural category, iconic tier. A Vietnamese public holiday and the country's largest family gathering of the year.

Origin

Le Tet - Tết Nguyên Đa, the festival of the first morning - falls on the first day of the first lunar month, the same date asLunar New Year across China, Korea and Mongolia. What distinguishes the Vietnamese form is duration and emphasis: it runs five days rather than one to three, and it is oriented almost entirely inward, toward the family and the ancestors.

The word Tet itself is a southern dialect term that displaced the northern nhat, which survives in Tết Nguyên Tiết, the Vietnamese New Year named in Quan cau and Kieu hai. The shift tracks the shift of Vietnamese political and cultural weight from the Red River delta to the south.

When it falls

Le Tet begins on the first day of the first lunar month. Tet 2026 is February 17. It falls on February 6 in 2027, January 26 in 2028, February 13 in 2029 and February 3 in 2030. Because it is lunar, the Gregorian date drifts about eleven days a year, so Tet can open as early as late January and as late as mid-February. The five-day break begins on the eve of Tet.

How it is observed

Households prepare an altar of offerings to the household and ancestral spirits on the seventh day of the final lunar month, and keep it through the holiday. A peach blossom, or in the south an apricot branch, goes in the corner as the emblem of spring. Every family makes banh chung - square glutinous-rice cakes wrapped in banana leaf and filled with pork, mung bean and salted egg yolk - often enough for dozens of families, and the making is the clearest signal that Tet is approaching.

The custom that most distinguishes Vietnam is duong tien, first footing: the first person to cross into the house in the new year sets its tone for the year. Families choose a lucky, healthy person deliberately, and avoid anyone whose horoscope clashes with the owner's. A modern alternative is to burn a symbolic pile of paper money at the threshold and send the first person in symbolically.

Visits then follow a strict order of seniority, usually over the first three days. Fireworks and parades exist in Vietnamese Tet but are far less central than in neighbouring countries; the festival is defined by cooking, visiting and paying respect.

Public status

Le Tet is a Vietnamese public holiday of five days. It is the country's dominant domestic travel period: the holiday is defined by the journey home, and motorway and railway traffic peaks in the days before it.

Where it is contested

Le Tet is not politically contested in any modern sense, but its northern and southern forms have periodically been read as a cultural marker of Vietnamese national unity. The northern Tet - with square banh chung and Tết Nguyên Tiết - and the southern Tet - with cylindrical banh tet and the term Tet - have both been presented as more authentically Vietnamese at different moments. The framing is mostly historiographic rather than political.
