A look at the lunisolar nature of the Chinese calendar and how it is used to track the phases of the Moon.
Understanding the Chinese calendar can be a fascinating exploration of ancient traditions and the significance of celestial bodies in marking the passage of time.
One intriguing question that often arises is, “How are the months and days of the Chinese calendar related to the phases of the Moon?”
To comprehend the connection, we must first dive into the intricacies of the Chinese calendar and its lunisolar nature.
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.
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.
Lunar Phases and Chinese Calendar Day Names
- New Moon: The first day of the month is called “Xin Yue” (literally “new moon”).
- Waxing Crescent: The second and third days of the month are called “Chu Shi” (literally “beginning of the day”).
- First Quarter Moon: The fourth day of the month is called “Sheng Yue” (literally “birth of the moon”).
- Waxing Gibbous Moon: The fifth to seventh days of the month is called “Shi Shi” (literally “middle of the day”).
- Full Moon: The eighth day of the month is called “Man Yue” (literally “full moon”).
- Waning Gibbous Moon: The ninth to eleventh days of the month are called “Yue Zhong” (literally “center of the moon”).
- Last Quarter Moon: The twelfth day of the month is called “Jie Yue” (literally “end of the moon”).
- Waning Crescent Moon: The thirteenth and fourteenth days of the month are called “Xu Shi” (literally “end of the day”).
These names are based on the phases of the Moon, and they are used to track the passage of time in the Chinese calendar. The names of the days also have symbolic meanings, and they are often used in poetry and literature.
