Moon Phase Calendar

What will the phase of the Moon be for your next Scout camp?

What will the phase of the Moon be for your next Scout camp? Perhaps you want a bright Moon to make flashlight-free walking easy. Or maybe you need it dark for stargazing. Whatever you want, this calendar will help you find the ideal date for your camp. Lunar eclipses are also shown.

In this calendar, the colour of each cell corresponds to the amount of light the moon will be giving off. Day numbers in bold indicate the day that contains the new moon, first quarter, full moon, or last quarter. Eclipses of the moon are marked in red.

The calculations are done with the PHP moon phase library by Stephen Zarkos, which is ported from Perl Astro::MoonPhase. I extend my appreciation to the many authors who contributed to these open-source software projects.
