Китайский лунно-солнечный календарь: полное руководство

Introduction

The Chinese Lunisolar Calendar — often called the lunar calendar in everyday speech — is one of the oldest continuous calendar systems in the world. It governs the timing of Chinese New Year, the Mid-Autumn Festival, the Dragon Boat Festival, and dozens of other cultural observances across East and Southeast Asia.

Lunisolar Structure

The Chinese calendar is built on lunar months of 29 or 30 days, synchronized with the solar year through periodic leap months — a process of Intercalation similar to the Hebrew Calendar. In most years, twelve lunar months are used; in leap years, a thirteenth month is inserted. The inserted month takes the same name as the month it follows, distinguished by the prefix 'leap' (run in Mandarin).

The 24 Solar Terms

Alongside the lunar months, the Chinese calendar divides the solar year into 24 solar terms (jieqi), each marking roughly 15 degrees of the sun's ecliptic longitude. These terms — including the spring Equinox, summer Solstice, and their counterparts — were originally designed to guide agricultural work: when to plant, irrigate, or harvest. They remain embedded in Chinese cultural consciousness and influence the timing of some traditional foods and practices.

Chinese New Year

Chinese New Year (Lunar New Year, or Spring Festival) is the most important celebration in the Chinese cultural calendar. It begins on the first day of the first lunar month, which falls between 21 January and 20 February on the Gregorian Calendar. The festival lasts fifteen days, culminating in the Lantern Festival on the first full moon of the lunar year. The year is also associated with one of twelve zodiac animals in a repeating cycle: Rat, Ox, Tiger, Rabbit, Dragon, Snake, Horse, Goat, Monkey, Rooster, Dog, and Pig. The animal cycle runs independently of both the lunar months and the intercalation cycle.

Mid-Autumn Festival

The Mid-Autumn Festival falls on the 15th day of the 8th lunar month, always a full moon. It is a harvest festival celebrated with mooncakes, lanterns, and family reunions. The date typically falls in September or October on the Gregorian calendar.

Regional Variations

Vietnam uses a closely related lunisolar system (the Vietnamese calendar) that differs slightly in intercalation rules, causing Tet — the Vietnamese New Year — to occasionally fall a day apart from Chinese New Year. Korea's Seollal and Japan's historical lunisolar calendar share the same structural roots, though Japan switched to a solar calendar in 1873.

Conclusion

The Chinese lunisolar calendar represents thousands of years of astronomical observation and agricultural necessity. Its dual solar-lunar structure keeps festivals tied to both the moon's cycle and the seasons, making it one of the most sophisticated timekeeping systems ever developed.
