How to Tell What Phase the Moon is in Today

Are you curious about what phase the moon is in today? Perhaps you want to plan a night hike, a stargazing session, or just want to observe the beauty of the moon. Whatever your reason, there are several easy ways to determine the current phase of the moon.

Check a Moon Phase Calendar or App

One of the simplest ways to find out the phase of the moon is to consult a moon phase calendar or app. These tools provide a clear visual representation of the moon’s phase, along with the date and time of the next full or new moon. You can find moon phase calendars online or download a moon phase app for your smartphone or tablet.

Observe the Moon

Another way to determine the current phase of the moon is to observe it directly. Look up at the night sky and locate the moon. Notice its shape and how much of it is illuminated. You can use a pair of binoculars or a telescope to get a closer look. Keep in mind that the moon’s phase changes slightly each night, so be sure to observe it at the same time each evening.

Use Your Fingers

If you don’t have access to a moon phase calendar or app and can’t observe the moon directly, you can use your fingers to estimate the moon’s phase. Hold up your hand and compare the shape of the moon to the curve of your fingers. For example, if the moon appears to be a thin crescent shape, it is likely in the early stages of a waxing crescent phase.

Consult an Astronomical Website

There are several astronomical websites that provide detailed information about the moon’s phase, including the percentage of illumination and the precise time of the next full or new moon. NASA includes a website you can use for reference.


In conclusion, there are several ways to determine the current phase of the moon, whether you prefer to consult a calendar or app, observe the moon directly, use your fingers, or consult an astronomical website. With these tools at your disposal, you can enjoy the beauty and wonder of the moon at any time.
