The 24 Solar Terms (二十四節氣)
The solar terms divide the solar year into 24 segments, each about 15 days. They guided Chinese agriculture for millennia and remain the framework for the lunar calendar, festivals, and date selection.
How the Chinese almanac works
The Tong Shu (通書)
The Chinese almanac has been published annually for over a thousand years. Each day is assigned a sexagenary stem-branch pair, and from this the day's suitable and unsuitable activities are derived.
Suitable and unsuitable
Activities marked "suitable" (宜 yí) are favored by the day's elemental configuration. Those marked "avoid" (忌 jì) are discouraged. These recommendations reflect the alignment of the day's energy with different types of human activity.
Zodiac clashes & hours
Each day's earthly branch clashes with one zodiac sign. Additionally, the 12 two-hour periods (時辰) each carry their own auspicious or inauspicious designation - useful for choosing the right time for important events.

Frequently Asked Questions
What is the Tong Shu (Chinese Almanac)?
The Tong Shu (通書) is the traditional Chinese almanac published annually for over a thousand years. Each day is assigned a sexagenary stem-branch pair from which suitable and unsuitable activities are derived, combining astronomy, the five elements, and centuries of observation.
What are auspicious hours (時辰)?
The Chinese day is divided into 12 two-hour periods called shichen (時辰), each governed by an earthly branch. Some hours are auspicious (吉) for important activities, while others are inauspicious (凶). Choosing the right hour adds precision to date selection for weddings, business openings, and other events.
What are the 24 Solar Terms?
The 24 solar terms (節氣) divide the year into 24 segments of about 15 days each, based on the sun's position. They guided Chinese agriculture for millennia and remain the framework for the lunar calendar, festivals, and date selection. Examples include the solstices, equinoxes, and seasonal markers like Grain Rain and Frost Descends.
Can I use this checker for a wedding or a business opening?
Yes, and the two weigh different things. A wedding looks hardest at the couple's zodiac signs. An opening also checks the owner's chart. Enter the date you are considering and read it against the people the decision rests on.
Is the auspicious date checker free?
Yes. The checker runs in your browser, needs no account, and works whether or not you subscribe. The email field is optional and separate: it sends the feng shui audit, not your date results.
