Project description

Last stable version (PyPI) build status


Chinese version(中文版) is provided.

LunarCalendar is a Lunar-Solar Converter, containing a number of lunar and solar festivals in China.

Korean, Japanese or Vietnamese lunar calendar is the same as Chinese calendar, but has different festivals. Korean, Japanese and Vietnamese festivals can be easily included, with their languages.

LunarCalendar supports a time range of 1900 to 2100, which may be enough for a long time. But if you have needs for a wider time range, you can use generate.html to extend it.

LunarCalendar is inspired by Lunar-Solar-Calendar-Converter.


  • Accurate raw data, synchronize with Microsolf’s ChineseLunisolarCalendar class

  • Easy to extend festivals and languages, supported both zh_hans and zh_hant

  • Included Lunar Festivals, such as: MidAutumn Festival, Chinese New Year Eve, DragonBoat Festivals

  • Included Solar Festivals without fixed dates, such as: Mother’s Day, Easter

  • Added legality check of the lunar and solar date

  • Supported 24 solar terms(立春/春分/清明/冬至等)


LunarCalendar can be installed from the PyPI with easy_install:

$ easy_install LunarCalendar

Or pip:

$ pip install LunarCalendar

If you encounter an error like command 'gcc' failed with exit status 1 while installing ephem, maybe you should install python-devel first. For CentOS:

$ yum install python-devel

For Ubuntu:

$ apt-get install python-dev

Console Commands

A console command called lunar-find can be used to find the date of the festival, using it’s chinese name. Default to this year. Supporting alias of the festival.

$ lunar-find 重阳
重阳节 on 2018: 2018-10-17

$ lunar-find 重陽節
重阳节 on 2018: 2018-10-17

$ lunar-find 登高节 2019
重阳节 on 2019: 2019-10-07

You can also print all included festivals or 24 solar terms by date asc with:

$ lunar-find all 2019
$ lunar-find festival 2012
$ lunar-find 节日 2012
$ lunar-find solarterm
$ lunar-find 节气


Solar to Lunar:

import datetime
from lunarcalendar import Converter, Solar, Lunar, DateNotExist

solar = Solar(2018, 1, 1)
lunar = Converter.Solar2Lunar(solar)
solar = Converter.Lunar2Solar(lunar)
print(solar.to_date(), type(solar.to_date()))

Lunar to Solar:

lunar = Lunar(2018, 2, 30, isleap=False)
solar = Converter.Lunar2Solar(lunar)
lunar = Converter.Solar2Lunar(solar)
print(lunar.to_date(), type(lunar.to_date()))
print(Lunar.from_date(, 4, 15)))

Legality check for solar and lunar date. 2018-2-15(Leap Month) does not exist, but 2012-4-4(Leap Month) exists:

Lunar(2012, 4, 4, isleap=True)  # date(2012, 5, 24)
    lunar = Lunar(2018, 2, 15, isleap=True)
except DateNotExist:
