How to Use the Moon Phase Calculator

The Moon Phase Calculator is a simple and interactive tool that helps you find out the moon’s phase, its illumination percentage, and the estimated moonrise and moonset times for any given date. Follow these easy steps to get started!


Step 1: Pick a Date

  1. Click on the date field to bring up the calendar.
  2. Select the date you want to check.
  3. The date will automatically update in the input field.

Step 2: Find Out the Moon Phase

  1. Once you’ve picked a date, click “Get Moon Phase”.
  2. The tool will show:
    • The moon phase (e.g., New Moon, Full Moon, Waxing Crescent, etc.).
    • A moon emoji matching the phase.
    • The illumination percentage (how much of the moon is visible).
    • The estimated moonrise and moonset times.

Step 3: Check Moonrise & Moonset Times

  • The moonrise and moonset times are displayed below the moon phase details.
  • These times are estimates based on your selected date and location (if provided).
  • If you need precise times, consider using an official astronomy resource.

Step 4: View the Monthly Moon Calendar

  • Below the moon details, you’ll find a Moon Cycle Calendar for the month.
  • Each day of the month is shown with its corresponding moon phase icon.
  • This helps you track the moon’s changes throughout the month.

Step 5: Use Your Location for More Accuracy (Optional)

  1. Click “Use My Location” to allow access to your coordinates.
  2. If granted, your latitude and longitude will be displayed.
  3. The tool will adjust the moonrise and moonset times accordingly.
  4. If denied, the tool will still work using general estimations.

Helpful Tips

  • Always select a date first before clicking “Get Moon Phase.”
  • For precise moonrise and moonset times, refer to NASA’s Moon API or similar resources.
  • If something looks off, refresh the page and check your location settings.
