Frequently Asked Questions

How are auspicious and inauspicious activities determined?
Traditional Huangli uses rules based on the Jianchu (建除) twelve day officers, the 28 lunar mansions (二十八宿), and the day's stem-branch relationship. These rules are folk traditions — they are labeled as such to distinguish culture from science.
What is the difference between the lunar and Gregorian calendar?
The Gregorian calendar is a solar calendar with 365/366 days per year. The Chinese lunar calendar is lunisolar — months follow the moon cycle (~29.5 days), and leap months (every ~3 years) keep it aligned with the solar year.
Why does the same Gregorian date have a different lunar date each year?
A lunar year of 12 synodic months is about 354 days — about 11 days shorter than the Gregorian year. This causes lunar dates to drift forward by about 11 days each year until a leap month pulls them back.
What does 'clash' (冲煞) mean?
'Clash' (冲) means the day's earthly branch is opposite to a specific zodiac sign's branch (six-clash relationship). 'Evil direction' (煞) indicates an inauspicious cardinal direction for the day. Both are traditional folk concepts.
Is the almanac data reliable? Are my queries uploaded?
All calculations run locally in your browser — date queries never leave your device. Lunar conversion is based on the Hong Kong Observatory's published tables and astronomical algorithms. Solar term timings use VSOP87/ELP2000 precision ephemerides.

About the Chinese Almanac

What Is the Huangli?

The Chinese Almanac (黄历 / 通胜) is a traditional daily calendar used for centuries to guide daily activities based on the lunisolar calendar, stem-branch cycle, and folk traditions.

Lunar vs Solar Calendar

The lunar calendar follows moon phases (synodic months of ~29.5 days), while the solar calendar follows the Earth's orbit. The Chinese calendar is lunisolar — it adds leap months (~every 3 years) to stay aligned with the seasons.

How Stem-Branch Works

The 10 Heavenly Stems and 12 Earthly Branches combine into a 60-day cycle (sexagenary cycle) used to mark years, months, days, and hours — forming the backbone of the traditional Chinese calendar system.

Solar Terms & the Almanac

The 24 solar terms mark key astronomical positions of the Sun along the ecliptic. They define the seasonal framework that governs the lunar calendar's leap month placement and traditional farming guidance.
