A month of lunar dates, seasonal terms and traditional day markers.
These are traditional almanac markers, not predictions or advice about what to do.
Today's lunar date will appear in your time zone after the page opens.
Lunar dates and solar-term dates use Beijing time, UTC+8; the Vietnamese page uses UTC+7.
The year and animal change at lunar New Year; the month pillar and day markers change on the calendar date of each solar jie term.
The six-day cycle follows the lunar month and day shown here; Japanese and Korean local lunar calendars can differ from this Chinese calendar.
Calendar rules and festival dates
The Hong Kong Observatory's Gregorian–lunar tables (https://www.hko.gov.hk/en/gts/time/conversion.htm) describe the Chinese calendar reference, and its solar-term explanation (https://www.hko.gov.hk/en/gts/time/24solarterms.htm) describes the seasonal divisions. The lunar calendar uses the site's checked 1900–2100 table; exact solar-term instants are calculated with Astronomy Engine, an MIT-licensed astronomical model.
The Vietnamese calendar uses UTC+7 new-moon and principal-term dates, with month 11 anchored to the winter solstice; the Chinese reference uses UTC+8. Hồ Ngọc Đức's Vietnamese calendar explanation (https://www.informatik.uni-leipzig.de/~duc/amlich/) discusses this regional difference. The page's animal year changes at lunar New Year, while month pillars use solar jie months.
Festival rules use regular lunar months: Lunar New Year 1/1, Lantern 1/15, Dragon Boat 5/5, Seventh Night 7/7, Ghost Festival 7/15, Mid-Autumn 8/15, Double Ninth 9/9 and Laba 12/8. New Year's Eve is the day before the next regular 1/1. Qingming and the winter solstice fall on their solar-term dates; festival names here are cultural labels rather than public-holiday schedules.
Traditional almanac markers and sources
The National Diet Library's calendar history (https://www.ndl.go.jp/koyomi/) provides background on Japanese calendar annotations. Rokuyo follows lunar month plus day modulo six: remainder 2 is Sensho, 3 Tomobiki, 4 Senbu, 5 Butsumetsu, 0 Taian and 1 Shakko; leap months repeat the base month number. Korean Son eopneun nal marks lunar days ending in 9 or 0. The National Folk Museum of Korea's folklore encyclopaedia (https://folkency.nfm.go.kr/) describes Korean folk-calendar traditions.
The public-domain Qing almanac treatise Xie Ji Bian Fang Shu describes traditional day gods and day officers. The MIT-licensed lunar project (https://github.com/6tail/lunar-javascript) provides a modern comparison of these conventions. Qing Long starts on Zi days in Yin/Shen months, Yin in Mao/You, Chen in Chen/Xu, Wu in Si/Hai, Shen in Zi/Wu and Xu in Chou/Wei; count forward through the twelve gods. Qing Long, Ming Tang, Jin Kui, Tian De, Yu Tang and Si Ming are yellow-path labels; the other six are black-path labels.
Jianchu starts with Jian when the day branch matches the solar month branch, then advances through Chu, Man, Ping, Ding, Zhi, Po, Wei, Cheng, Shou, Kai and Bi. Month markers change on the civil date of a jie term. These traditional classifications give no scientific basis for predictions or advice about activities.

Frequently asked questions
What is the lunar calendar?
The Chinese calendar is lunisolar: months begin with a new moon, while solar terms keep the year aligned with the seasons. A month has 29 or 30 days, and a year has 12 or 13 months. This page pairs those dates with a Gregorian month grid.
What is a leap month?
A leap month repeats the number of the preceding lunar month to keep the calendar aligned with the solar year. The month containing the winter solstice is month 11; when there are 13 months between successive winter-solstice months, the first month without a principal solar term is the leap month. Lunar festivals are marked in the regular month, not repeated in its leap month.
What are Rokuyo, Son eopneun nal and Huangdao days?
Rokuyo is a traditional six-label cycle calculated from the lunar month and day. Korean Son eopneun nal marks lunar days 9, 10, 19, 20, 29 and 30. Huangdao and Heidao classify six day gods each in a twelve-god cycle, while Jianchu is a separate twelve-officer cycle. These are cultural traditions rather than evidence about good or bad outcomes; this page gives no predictions or lists of recommended activities.
Why does the year of the animal change at lunar New Year here?
Calendars commonly label the animal year from lunar New Year, so the year stem-branch and animal in this view use that boundary. Four Pillars astrology uses Start of Spring instead. The month stem-branch here follows the solar jie months and uses the Start-of-Spring year for its stem calculation, even during the days before lunar New Year.
Which time zone does this calendar use?
Today is the current civil date on your device. Chinese lunar dates and solar-term dates are computed with Beijing time, UTC+8. On the Vietnamese page, both use UTC+7, the reference for Vietnam's official lunar calendar; this can change a month start and even the New Year, as in 1985, when Tết was on 21 January while Chinese New Year was on 20 February. Solar-term times are shown in the same reference zone.
Do the Japanese and Korean labels use separate national calendars?
The marker labels follow the lunar dates shown on this page, using the Chinese calendar at UTC+8 or the Vietnamese calendar at UTC+7. Japan's old calendar and Korean local calendar can differ on some dates; use the dedicated Rokuyo calendar when you need Japanese old-calendar dates.
When do month markers change?
This date-only almanac changes the month pillar, day god and day officer on the civil date containing each of the twelve solar jie terms. A principal term in between does not change the month. Birth charts use the exact term instant instead, so a chart for a time early on a boundary day can have a different month pillar.
