The calendar below shows the phase of the moon for each day of the selected month. You can change the month and year to whatever you like between January 3999 BC and December 3999 AD.

This version of the Moon Calendar uses HTML 5, Javascript, and SVG. It replaces the Java-based version of the calendar, which is still available here.

Hovering your mouse over any day in the calendar will display a popup showing the moon's distance, phase and other information.

Instructions on what the various controls do is found below. There is also a reference section for those interested in the algorithms used.

Feel free to with your thoughts on the program.

You are using a browser that does not support SVG. This page relies heavily on SVG and other features that are not supported in older browser versions. Please consider upgrading to a more current browser.

The original Java-based version of the Moon Calendar remains available here.
