The Chinese Calendar: An Introduction

The Chinese calendar is unique in its composition, primarily based on both the Moon’s phases and the Sun’s yearly cycle.

As such, it is often referred to as a lunisolar calendar.

It is this distinct structure that allows the months and days of the Chinese calendar to closely track the Moon’s various phases.

Key Features of the Chinese Calendar

  • Lunisolar Structure: The Chinese calendar is a lunisolar calendar, taking into account both the phases of the moon and the time of the solar year.
  • Start of the Year: The Chinese New Year (also known as the Spring Festival) marks the start of the Chinese calendar. It falls between January 21 and February 20, depending on the lunar cycle.
  • Months: Each Chinese calendar year consists of 12 or 13 months. Each month begins with the new moon and lasts until the next new moon, typically 29 or 30 days.
  • Leap Month: To realign the calendar with the solar year, an extra month, or “leap month,” is added to the Chinese calendar approximately every three years.
  • Days: Each month is divided into “big” and “small” days. Big days have 30 days, while small days have 29 days, reflecting the lunar cycle.
  • Cultural Significance: The Chinese calendar is rich in cultural and historical significance, with many traditional festivals and events based on its dates, such as the Mid-Autumn Festival and the Dragon Boat Festival.
  • Zodiac Animals: Each year in the Chinese calendar is associated with one of 12 animals in the Chinese zodiac, repeating in a 12-year cycle.
  • Solar Terms: The Chinese calendar also includes 24 solar terms, which are specific points in the solar cycle used for agricultural purposes.
  • Traditional Use: Despite the widespread use of the Gregorian calendar for practical and administrative purposes, the Chinese calendar is still used for marking traditional holidays, choosing auspicious days for weddings, funerals, or business openings, and in astrology.
Phases of the Moon

The Phases of the Moon and Their Significance in the Chinese Calendar

The Moon has various phases, and each of these holds significance in the Chinese calendar.

They are the new moon, the first quarter moon, the full moon, and the last quarter moon.

The new moon represents the start of a new lunar month.

The first and last quarters divide the lunar month into halves, while the full moon indicates the middle of the lunar month.

This correlation helps in understanding how the days and months of the Chinese calendar are related to the Moon’s phases.

Moreover, the moon’s influence extends beyond mere calendars and timekeeping. If you’re curious about how the moon might directly impact us as humans, don’t miss out on our article, How and Does the Moon Affect Humans? It explores some intriguing theories and scientific studies on this topic.

How the Chinese Calendar Months Relate to the Moon’s Phases

The Chinese calendar months correspond directly to lunar cycles, divided into either 29 or 30 days.

A month begins at the sighting of a new moon and ends when the next new moon appears.

Thus, the full moon, marking the lunar month’s midpoint, always occurs around the 15th day of the lunar month.

Naming the Days After the Phases of the Moon

Interestingly, the days of the Chinese calendar also correlate to the Moon’s phases.

For example, the term ‘chū shí’ is used to denote the day of the new moon, while ‘shí wǔ’ represents the day of the full moon.

This nomenclature not only links the calendar days to the lunar cycle but also reinforces the cultural significance of the Moon’s phases in Chinese society.
