Vietnam measures its festival calendar through two parallel systems. The Gregorian calendar governs civic holidays fixed to solar dates. The lunar calendar determines traditional festivals that shift annually by up to four weeks in Gregorian terms. Most Vietnamese observe both calendars simultaneously, maintaining Gregorian dates for administrative purposes while calculating traditional celebrations using lunar months that begin with each new moon. This dual system means a Vietnamese person born on Gregorian April 15 celebrates their official birthday on that date while also observing their lunar birth date, which falls on a different Gregorian date each year.
Tết Nguyên Đán, universally shortened to Tết, occupies the first three days of the first lunar month, typically falling between January 21 and February 20 in Gregorian terms. The 2024 Tết begins February 10, marking the Year of the Dragon. Vietnamese tradition grants Tết seven official preparation days before the lunar new year and three official celebration days after, though many businesses close for ten to fifteen days total. The scale exceeds all other Vietnamese celebrations combined. Hanoi and Ho Chi Minh City populations drop by an estimated forty percent as residents return to ancestral villages. Domestic flights during the week before Tết cost three to five times standard fares, with trains and buses operating at maximum capacity for roughly two weeks surrounding the holiday. The Reunification Express train from Hanoi to Ho Chi Minh City, normally bookable same-day during off-peak periods, requires reservations forty-five to sixty days in advance for Tết travel periods.
Tết preparations follow specific dates in the final lunar month of the year. Tết Táo Quân falls on the twenty-third day of the twelfth lunar month, typically one week before the new year. Vietnamese tradition holds that the Kitchen God departs each household on this date to report the family's behavior to the Jade Emperor. Families prepare offerings of carp fish, which the Kitchen God rides to heaven, releasing live carp into rivers and lakes throughout Vietnam on this single day. Hanoi authorities in 2019 requested residents stop releasing carp into Hoàn Kiếm Lake after water quality monitoring showed the lake received approximately 150,000 carp during Táo Quân, exceeding ecosystem capacity. The actual new year's eve, called Giao Thừa, centers on the precise moment the new year begins, calculated by lunar astronomers and announced through national media. Families gather at this exact minute, often midnight but occasionally occurring as early as 11:00 PM or as late as 1:00 AM Gregorian time.
The Tết celebration contains specific mandatory activities distributed across its first three days. Xông Đất, the first-footer tradition, requires that the first person entering a home after the new year arrives possesses favorable characteristics. Middle-aged men with successful careers, happy marriages, and living parents represent ideal first-footers. Families pre-arrange these visits, sometimes paying modest fees to particularly auspicious individuals. The first day reserves itself for paternal family visits. The second day obligates visits to maternal families. The third day encompasses visits to teachers, mentors, and professional superiors. These customs apply across Vietnamese society regardless of urbanization or economic status. A 2018 survey by the Vietnam General Statistics Office found that eighty-seven percent of Vietnamese respondents maintained these three-day visit patterns despite living in nuclear families separated from extended relatives.
Tết observances prohibit specific activities during the first three days. Vietnamese tradition forbids sweeping floors, which might sweep away good fortune, during this period. Breaking objects, arguing, wearing black or white clothing, and discussing death remain prohibited. Parents avoid scolding children. Debt collectors suspend operations. Many Vietnamese believe the first week of Tết determines fortune for the entire year, creating widespread anxiety about inauspicious events. The Vietnamese government maintains mandatory three-day closure for all public sector offices, though private businesses follow their own schedules. Banks close for five to seven days. International schools frequented by expatriate families typically provide ten to twelve days of Tết holiday.
Tết food preparation begins weeks before the holiday. Bánh Chưng, square glutinous rice cakes filled with mung bean paste and pork, require twelve to fourteen hours of continuous boiling. Northern Vietnamese families consider bánh chưng mandatory, with most families preparing ten to thirty cakes. Southern Vietnamese substitute cylindrical bánh tét using identical ingredients in different shapes. The cakes symbolize earth through their square shape and ingredients representing agricultural abundance. Families also prepare mứt, candied fruits and vegetables including kumquat, coconut, ginger, and lotus seed, displayed in decorative containers throughout Tết. Each household stocks fresh flowers specific to their region. Northern families purchase peach blossoms (hoa đào), southern families buy apricot blossoms (hoa mai), and central Vietnamese select both. A single branch of peach blossoms in Hanoi markets costs 200,000 to 2,000,000 Vietnamese đồng depending on size and bloom density, representing significant household expense when average Hanoi monthly income measures approximately 7,000,000 đồng.
Vietnamese children receive lì xì, red envelopes containing money, from elders during Tết. The practice extends beyond immediate family to include any child visiting the household. Typical lì xì amounts range from 10,000 to 500,000 đồng per envelope, with most families preparing dozens of envelopes. The red color represents luck and prosperity, while even numbers of currency notes within each envelope symbolize balance and harmony. Adults also exchange lì xì with elderly parents and grandparents, reversing the giver-receiver relationship. Unmarried adults traditionally receive lì xì regardless of age, creating situations where forty-year-old unmarried individuals receive red envelopes from married younger siblings.
Tết Nguyên Đán's economic impact dominates Vietnamese commerce. The Vietnam Retail Association reported that Tết 2023 generated 42 trillion đồng in retail sales during the two weeks surrounding the holiday, representing approximately twelve percent of annual retail turnover compressed into four percent of calendar time. Domestic tourism during Tết 2023 recorded 6.8 million trips according to the Vietnam National Administration of Tourism, with average spending per trip reaching 3.5 million đồng. Flower markets operating in major cities during the final week before Tết attract hundreds of thousands of visitors. The Quảng Bá flower market in Hanoi operates twenty-four hours daily during the five days preceding Tết, with peak traffic occurring between midnight and 4:00 AM as wholesalers and retailers conduct transactions.
Tết Nguyên Đán differs substantially from Chinese New Year despite sharing lunar calendar foundations. Vietnam banned Chinese New Year celebrations during the post-1975 socialist period, compelling Vietnamese of Chinese descent to observe only Vietnamese Tết. The ban lifted in 1986 during Đổi Mới economic reforms, but most Vietnamese-Chinese continue observing only Tết rather than separate Chinese New Year celebrations. Vietnamese Tết preparations emphasize bánh chưng while Chinese traditions center on dumplings. Vietnamese families display peach or apricot blossoms while Chinese traditions favor plum blossoms. The phrase "Chúc mừng năm mới" serves as the standard Vietnamese Tết greeting, distinct from Chinese equivalents.
Hùng Kings' Commemoration Day, called Giỗ Tổ Hùng Vương, falls on the tenth day of the third lunar month, typically landing in March or April. The 2024 observance occurs April 18 in Gregorian terms. This national holiday honors the Hùng Kings, legendary rulers of Văn Lang, considered Vietnam's first state existing from approximately 2879 BCE to 258 BCE according to Vietnamese historical tradition. The Hùng Kings Temple in Phú Thọ Province, located roughly ninety kilometers northwest of Hanoi, becomes Vietnam's most visited site on this specific day. The Vietnam News Agency reported that 2023 Hùng Kings' Day drew approximately five million visitors to Phú Thọ Province during the three-day period surrounding the official holiday, overwhelming the province's population of 1.4 million.
The Hùng Kings Temple complex contains fourteen structures ascending Nghĩa Lĩnh Mountain across multiple terraces. The main temple sits at 175 meters elevation. Visitors ascending to the temple during Hùng Kings' Day typically wait two to four hours in queues extending several kilometers down the mountain. Provincial authorities install temporary lighting allowing overnight climbing to reduce daytime congestion. The ceremony at the main temple follows precise ritual protocols. Government delegations led by senior Communist Party officials perform offerings beginning at 6:00 AM. Offerings include bánh chưng, bánh dày (round white rice cakes), betel and areca, fresh fruit, and incense. The ceremony incorporates traditional music performed on đàn tranh (sixteen-string zither), đàn bầu (monochord), and drums.
Vietnam celebrates Liberation Day on April 30, commemorating April 30, 1975, when North Vietnamese tanks entered Saigon, ending the Vietnam War. The official name is Reunification Day, though many Vietnamese still use Liberation Day. This date became a national holiday immediately after 1975. Government ceremonies occur at the Reunification Palace in Ho Chi Minh City, the exact location where North Vietnamese tank number 843 crashed through gates at 10:45 AM on April 30, 1975. The tank remains displayed on the palace grounds. Official observances include military parades in Hanoi and Ho Chi Minh City during milestone anniversaries. The fortieth anniversary in 2015 featured a parade involving 30,000 participants along Hanoi's Điện Biên Phủ Street. Non-milestone years typically feature smaller ceremonies limited to wreath-laying at war memorials.
International Workers' Day on May 1 always follows immediately after Liberation Day, creating a guaranteed two-day holiday minimum. The Vietnamese government frequently extends this to a four or five-day weekend by declaring additional bridge days. The 2024 celebration creates a four-day weekend from April 30 to May 3 after the government declared May 2 and 3 as compensatory holidays. This extended break generates significant domestic tourism, with Da Lat, Nha Trang, Vung Tau, and Da Nang experiencing hotel occupancy rates above ninety percent. Vietnam Airlines and VietJet Air typically add 200 to 300 additional domestic flights during this period compared to regular weeks.
National Day falls on September 2, marking September 2, 1945, when Hồ Chí Minh read the Declaration of Independence in Hanoi's Ba Đình Square, establishing the Democratic Republic of Vietnam. The ceremony occurred at precisely 2:00 PM before an estimated crowd of 400,000 people. Hồ Chí Minh opened the declaration by directly quoting the 1776 American Declaration of Independence. The full text appears in the Vietnamese Declaration of Independence, which begins "All men are created equal. They are endowed by their Creator with certain inalienable rights; among these are Life, Liberty, and the pursuit of Happiness." Ba Đình Square hosts annual National Day ceremonies attended by senior government officials, military representatives, and selected public attendees. The square accommodates approximately 50,000 people. Milestone anniversaries feature military parades. The seventieth anniversary in 2015 included 30,000 military personnel, 84 aircraft, and 500 military vehicles.
National Day observance extends beyond Hanoi to all provincial capitals. Government buildings nationwide display Vietnamese flags, required by decree to measure at least two meters in length for public buildings. Fireworks displays occur in major cities. Hanoi launched fireworks from thirty locations during the 2023 National Day celebration, beginning at 9:00 PM and continuing for fifteen minutes. Ho Chi Minh City synchronized fireworks from twenty locations along the Saigon River. Smaller cities typically feature single-location displays. The government allocates budget for these celebrations annually, with spending increasing during milestone years. Television broadcasts of National Day ceremonies on Vietnam Television (VTV) typically achieve viewership above sixty percent of television-equipped households.
Wandering Souls Day, called Tết Trung Nguyên or Lễ Vu Lan, occupies the fifteenth day of the seventh lunar month, falling in August or September. The 2024 observance occurs August 22 in Gregorian terms. Buddhist tradition holds that the gates of hell open on the first day of the seventh lunar month, releasing souls to wander earth for the entire month before returning on the thirtieth day. The fifteenth day marks the peak of this period. Vietnamese families prepare elaborate food offerings placed on outdoor altars, feeding both ancestral spirits and wandering souls without descendants to care for them. The offerings deliberately exceed household needs, with families preparing five to seven dishes including rice, meat, vegetables, fruit, and sweet desserts.
Vu Lan ceremonies in Vietnamese pagodas emphasize maternal devotion. The tradition derives from the Buddhist Ullambana Sutra describing Mục Kiền Liên, a disciple of Buddha, rescuing his mother from hell. Vietnamese Buddhists wear roses during Vu Lan. Red roses indicate living mothers. White roses indicate deceased mothers. The practice originated at Xá Lợi Pagoda in Ho Chi Minh City in 1962, introduced by monk Thích Đức Nhuận. The custom spread nationwide within five years. Contemporary Vu Lan observances at major pagodas attract thousands of participants. Thiên Mụ Pagoda in Hue reported 12,000 visitors during the 2023 Vu Lan ceremony. Trấn Quốc Pagoda in Hanoi distributed 8,000 roses during its 2023 observance.
Wandering Souls Day carries practical restrictions on activities. Vietnamese tradition discourages marriage ceremonies, business openings, house purchases, and long-distance travel during the seventh lunar month, particularly around the fifteenth day. Real estate agents in major Vietnamese cities report that property transactions drop forty to fifty percent during this month compared to adjacent months. Wedding venues experience similar declines. A 2019 survey by Vietravel, one of Vietnam's largest travel companies, found that domestic tourism bookings during the seventh lunar month measured thirty-five percent below average monthly levels. Many Vietnamese avoid swimming during this month, believing that wandering souls might pull swimmers underwater. Coastal cities report noticeably reduced beach attendance during this period despite favorable weather conditions.
Mid-Autumn Festival, called Tết Trung Thu, falls on the fifteenth day of the eighth lunar month, occurring in September or October. The 2024 celebration happens September 17 in Gregorian terms. Unlike most Vietnamese festivals honoring ancestors or historical events, Mid-Autumn Festival focuses specifically on children. The festival originated during the Lý Dynasty, 1010-1225 CE, as a harvest celebration coinciding with the full moon when agricultural work decreased, allowing parents to spend time with children. Contemporary observance maintains this child-centered focus. Parents purchase lanterns, toys, and mooncakes for children. Schools organize lantern parades. Shopping districts in Hanoi and Ho Chi Minh City install elaborate decorations during the two weeks preceding the festival.
Mooncakes dominate Mid-Autumn Festival commerce. These dense pastries contain sweet or savory fillings surrounded by thin crusted exteriors stamped with decorative patterns. Traditional fillings include lotus seed paste, mung bean paste, and mixed nuts. Each cake measures approximately ten centimeters in diameter and weighs 150 to 250 grams. Modern variations incorporate chocolate, coffee, durian, and ice cream fillings. Mooncakes function primarily as gifts rather than food for personal consumption. Companies purchase thousands of mooncakes as gifts for employees, clients, and business partners. The Vietnam Baking Association reported that 2023 mooncake sales reached 5.6 trillion đồng, with production concentrated in the forty-five days before Mid-Autumn Festival. Kinh Do, Vietnam's largest mooncake manufacturer, produces approximately twelve million cakes annually, representing roughly fifteen percent of market share.
Mooncake pricing varies dramatically based on ingredients and brand prestige. Standard mooncakes from local bakeries cost 30,000 to 60,000 đồng each. Premium mooncakes from established brands like Kinh Do, Brodard, or Givral reach 80,000 to 150,000 đồng per cake. Luxury mooncakes marketed by international hotels cost 200,000 to 500,000 đồng each. These luxury versions typically come in decorative boxes containing four to six cakes, with total package prices reaching 2,000,000 to 3,000,000 đồng. The packaging often costs more than the cakes themselves. Companies market mooncake boxes as status symbols, with gift-givers selecting boxes primarily for social signaling rather than cake quality.
Children's lanterns for Mid-Autumn Festival range from simple paper versions costing 20,000 đồng to elaborate plastic battery-powered models reaching 300,000 đồng. Traditional lanterns take five-pointed star shapes made from cellophane paper stretched over bamboo frames, with candles providing illumination. Safety concerns have shifted most families toward electric lanterns. The Hanoi Old Quarter, particularly Hàng Mã Street, becomes Vietnam's largest lantern market during the month before Mid-Autumn Festival. Vendors occupy every available sidewalk space along the 400-meter street length. Weekend crowds during the two weeks before the festival can take thirty minutes to walk this normally five-minute distance.
