Frequently Asked Questions
How long is a lunar cycle?
A complete lunar cycle (from new moon to new moon) lasts approximately 29.53 days. This is known as a synodic month.
What causes moon phases?
Moon phases are caused by the relative positions of the Earth, Moon, and Sun. As the Moon orbits Earth, different portions of its sunlit side are visible to us.
What is illumination?
Illumination refers to the percentage of the Moon's surface that is lit by the Sun as seen from Earth. A full moon is 100% illuminated, while a new moon is 0% illuminated.
How to Use the Moon Phase Calculator
Simply select any date from the calendar to find the exact phase of the lunar cycle. The tool automatically calculates the moon's position relative to Earth and Sun using high-precision astronomical algorithms. You will instantly see the phase name (like Full Moon, Waxing Crescent, or Third Quarter), a visual representation, and the percentage of surface illumination. It's designed to work for both past events and future planning.
