Mooncake day is a popular name for the Mid-Autumn Festival, which falls on the 15th day of the eighth lunar month, when the moon is full. On the Gregorian calendar that is a date in September or early October, and in 2027 it is Wednesday, September 15. People eat mooncakes, drink tea and share fruit with family.
What is mooncake day?
Mooncake day is the informal English name for the Mid-Autumn Festival, a family holiday built around the full moon and the pastry that gives it the nickname. The same festival is also called the Moon Festival and the Mooncake Festival.
The holiday is observed in China, Hong Kong, Taiwan, Vietnam, Singapore, Malaysia and in Chinese communities overseas. In Vietnam it is known as Tet Trung Thu and is especially centered on children and lanterns. The mooncake is the common thread across these places, though fillings and customs differ.
When is the Mid-Autumn Festival in 2026 and 2027?
The Mid-Autumn Festival fell on Friday, September 25, 2026, and falls on Wednesday, September 15, 2027. Each date is the 15th day of the eighth Chinese lunar month.
| Year | Date of the festival | Day of the week |
|---|---|---|
| 2024 | September 17 | Tuesday |
| 2025 | October 6 | Monday |
| 2026 | September 25 | Friday |
| 2027 | September 15 | Wednesday |
Check a current calendar for later years. In the United States, dates in the Gregorian calendar are the ones to use, but the festival is observed the same evening as the full moon in China.
Why does the date change every year?
The date changes because the festival follows the Chinese lunar calendar, which tracks the moon, while the Gregorian calendar tracks the sun. A lunar month starts at the new moon, so the 15th day lands near the full moon.
The lunar year is shorter than the solar year, so dates drift earlier by about eleven days each year. Every few years a leap month is added to bring the calendars back in line, and the festival then jumps later. That is why the festival can be as early as the second week of September or as late as early October.
What do people eat on mooncake day?
People eat mooncakes above all, with tea, and add seasonal fruit and sweets around them. The classic table includes pomelo, grapes, pears, persimmons and sometimes taro or water chestnut dishes.
- Mooncakes: baked Cantonese style, flaky styles and chilled snow skin styles
- Fruit: pomelo, grapes, pears, persimmons and apples
- Tea: oolong, jasmine, pu-erh or chrysanthemum
- Sweets: osmanthus jelly, sesame sweets and rice-based desserts
Menus are family-specific. Some households keep to one favorite mooncake bought every year, while others try a new filling each season.
How do you buy mooncakes ahead of the festival?
Buy mooncakes about one to two weeks before the festival, choose the filling you want, and ask how long the pastry keeps. Boxes sell fastest in the days just before the date, especially popular fillings such as lotus seed paste.
- Decide how many you need: one per household as a gift, or several for gatherings.
- Choose fillings for each recipient. Lotus seed paste and red bean paste suit most people.
- Check whether a salted egg yolk is included, since some guests prefer plain paste.
- Ask about shelf life and storage.
- Wrap or box the mooncakes for gifting, and plan to deliver a few days before the festival.
What do you say or give on mooncake day?
A box of mooncakes is the standard gift, often given with a short greeting wishing a happy Mid-Autumn Festival. In Mandarin the greeting is Zhongqiu jie kuaile, and in Cantonese it is Jung chau jit faai lok.
Gift boxes go to relatives, friends, neighbors and colleagues, and the exchange goes both ways in many communities. A small box with two kinds of paste is a safe choice when you do not know someone’s tastes.
How is mooncake day celebrated in the United States?
In the United States, mooncake day is usually celebrated in the evening with family or friends, since it is not a day off. People gather for dinner, share mooncakes and tea and, where the sky allows, step outside to see the moon.
Chinatowns in Boston, New York and San Francisco see more shoppers at bakeries and grocers in the days before the festival. Community groups and cultural associations sometimes hold lantern events or moon-viewing gatherings, though what is offered changes each year, so check local listings. Students far from home often mark the day with a single mooncake shared among friends, which keeps the custom of togetherness alive.
What sizes and types of mooncake can you buy?
Mooncakes come as single pieces, small wrapped pieces and gift boxes, and the style depends on the bakery. A traditional baked mooncake is palm-sized and heavy for its size, because the paste is dense.
| Type | Skin | Serving style | Best for |
|---|---|---|---|
| Cantonese baked | Thin, golden, molded | Cut into wedges | Classic gifting and sharing |
| Flaky Suzhou style | Layered pastry | Eaten warm or at room temperature | A lighter, crisp bite |
| Snow skin | Soft, chilled, chewy | Served cold | A modern, softer taste |
| Mini mooncakes | Varies | One or two bites | Tasting several fillings |
A single large mooncake can serve a table. Mini versions suit people who want to try more than one filling without committing to a whole cake.
What should you know before you eat mooncakes?
Mooncakes are rich and dense, so small portions are the norm, and allergies deserve a check. Nuts, seeds, soy and egg are common ingredients, and the skin often contains wheat.
- Ask about nuts and seeds in the filling if anyone at the table has an allergy.
- Ask the baker about ingredients, since recipes differ between bakeries.
- Serve tea alongside, as the pastry is sweet and heavy.
- For dietary or religious questions, ask the baker directly, because a guide cannot answer them for a specific shop.
