A small JavaScript library for converting between the Chinese lunar calendar and the Gregorian (solar) calendar. It also returns supplementary data such as heavenly stems and earthly branches (Gan-Zhi), zodiac animals, solar terms, and astrological signs.
Use cases
- convert a Gregorian date to Chinese lunar date
- convert lunar date to solar date in JavaScript
- get Chinese zodiac animal for a birth year
- display lunar dates in a Chinese calendar app
- compute heavenly stems and earthly branches for a date
- find solar terms for a given lunar month
When to choose
- you need lightweight lunar/Gregorian conversion in JavaScript without dependencies
- you want lunar calendar metadata like Gan-Zhi, zodiac, and solar terms
- you are building a Chinese-language app that shows traditional dates
When to avoid
- you need calendars other than Chinese lunar and Gregorian
- you need a full-featured calendar UI component rather than a conversion library
- you need non-JavaScript language support
