Chinese Almanac — auspicious days online
Day quality with the reasoning shown: sexagenary pillars, solar terms, the 28 lunar mansions, auspicious hours, the clashing sign of the day, and festivals. Free, no sign-up.
What the almanac shows
- Pillars of the day — year, month, day and hour in the sexagenary cycle, with their Na Yin elements.
- Solar term — which term the day falls in, when it began and when the next one starts.
- Day rating — a score with the contributing factors listed, so you can see why a day scores well or badly instead of trusting a verdict.
- Auspicious hours, the clashing sign of the day, and the directions of the wealth, joy and blessing gods.
- Flying stars of the year, month and day across the nine palaces.
Why a day can be “good” and still not be your day
A day rating is general. Two further filters are personal, and both matter more than the score:
- The clash. Each day clashes with one zodiac sign. If it clashes with yours, most traditions say to avoid starting something important that day whatever the general score says.
- The task. Classical day selection rates a day for a purpose — travelling, opening a business, a wedding, breaking ground. A day can be excellent for one and poor for another.

Frequently asked questions
What is a solar term?
One of twenty-four divisions of the solar year, defined by the Sun’s position along the ecliptic. They — not the lunar months — govern the seasons in Chinese calendrical work, and they decide the month pillar in BaZi.
What are the 28 lunar mansions?
A division of the sky along the Moon’s path into twenty-eight segments, each with a name and a traditional character. In day selection each date is assigned one mansion, and some are considered favourable for particular activities.
Why do two almanacs disagree about the same day?
Because almanac traditions differ in which factors they weigh and how heavily. This tool shows the contributing factors rather than only a verdict, so you can see where a disagreement comes from.
Which calendar should I enter?
Gregorian. The lunar date, the sexagenary pillars and the solar term are all derived for you.
