Moon Phase Calendars

Our popular Moon Phase Calendars are still available here at!

You can click the button below or navigate to Resources -> Online Resources and click on “More Information and Links” under The Moon heading. The link to our Moon Phase Calendars is right at the top.

These easy to use calendars will help you find the next moonless night for good observing conditions. On the other hand, if you are interested in observing the moon in close detail the calendars will help you schedule that too. These calendars can be used to find the next full moon, or a date when the terminator will be close to a desired location.
