Lunisolar Calendar

The Lunisolar Calendar Chrome extension offers a unique date tracking tool that reflects both the moon phases and the solar year, integrating cultural lunisolar timekeeping traditions. It accurately indicates the season based on a tropical year or predicts full moon positions near constellations using a sidereal year framework.

This calendar adapts to the natural cycles by alternating ordinary years with 12 months and embolismic years that add a 13th intercalary month to maintain synchronization with lunar and solar periods. Ideal for users interested in astronomy, cultural calendars, or planning around lunar and solar events, this extension provides an insightful and reliable way to follow complex calendrical systems directly in your browser.
