How to use
In “Solar to lunar conversion” enter any date and choose an hour to get the lunar date, the four pillars and the zodiac animal. The “Monthly almanac” lays out a whole month; click a cell to jump to it. “Lunar to solar lookup” works the other way round. “Lunar festival lookup” lists the exact solar dates of Chinese New Year, Lantern, Dragon Boat, Qixi, Mid-Autumn, Double Ninth, Laba and New Year’s Eve for the chosen year.
FAQ
Why can the pillars disagree with other sources?
Here the year pillar changes at the first day of the lunar new year, the common folk convention. Some schools of Chinese astrology change it at the Start of Spring instead, so a date close to the boundary can carry a different year pillar. If you follow the solar-term convention, compare the Start of Spring date for that year yourself.
How are leap months marked?
A lunar year normally has twelve months and roughly every nineteen years it gains an extra leap month. The “Leap month” row states whether the selected year has one and which month it is; the month grid labels it as “Leap month N”.
Is the data accurate?
The lunar data uses the standard compressed calendar table for 1900 to 2100, cross-checked against each year’s Chinese New Year date, known leap months and day-pillar reference points, plus a 3,000-date round-trip consistency test between the solar and lunar calendars.
Is my data uploaded?
No. Every conversion runs in your browser and nothing is sent to a server, so it works offline too.
Why does the day pillar roll over at 23:00?
The Zi hour spans 23:00 to 00:59 and crosses midnight. Charts traditionally either change the day at that point or keep it. This tool uses the more common changing convention, so after 23:00 the day pillar already belongs to the next day.
示例与注意事项Example & notes
一个例子A worked example
查 2024 年春节：输入 2024-02-10，得到「甲辰年 正月初一」，年干支甲辰、生肖龙、日干支甲辰；同一天在月历里也能一眼看到「春节」标记。Looking up Chinese New Year 2024: enter 2024-02-10 and you get “甲辰年 正月初一”, year pillar 甲辰, zodiac Dragon, day pillar 甲辰 — and the month grid flags the same day as “Spring Festival”.
注意事项Things to watch
- 年干支以农历正月初一换年；若按立春换年的命理口径，1 月、2 月初的日期可能落在不同干支年。The year pillar changes at the first day of the lunar new year; under the solar-term convention used by some schools, January and early February dates can land in a different pillar year.
- 闰月约每 19 年出现一次，闰月当年会出现「闰二月」「闰五月」这样的月份，忽略闰月就会整体错位一个月。A leap month appears roughly every 19 years and adds an extra “Leap month N” — missing it shifts every later date by a month.
- 子时横跨午夜（23:00 至次日 00:59），本工具按换日口径计算，23:00 之后的日柱已属次日。The Zi hour crosses midnight (23:00 to 00:59); this tool rolls the day over at that point, so after 23:00 the day pillar already belongs to the next day.
- 覆盖范围为 1900-01-31 至 2100-12-31；更早或更晚的年份没有可靠的农历数据，页面会直接提示超范围。The supported range is 31 Jan 1900 to 31 Dec 2100; outside it there is no reliable lunar table and the page says so instead of guessing.
相关问答More Q&A
为什么查不到某些年份？Why are some years unavailable?
农历闰月规律本身就有周期误差，且各家历书在远古年份并不一致，本工具只覆盖 1900—2100 年标准历表区间。The leap-month cycle itself drifts, and old almanacs disagree about distant years, so this tool only covers the standard table from 1900 to 2100.
页面会给出运势或吉凶吗？Does the page give fortune or lucky-unlucky readings?
不会。本页只做历法换算与客观对应关系展示，不含任何运势推断或吉凶判断。No. The page only converts between calendars and states objective correspondences — it makes no fortune or auspiciousness claims.
