The Moon’s phases are determined by its position relative to the Earth and Sun. A new moon occurs when the Moon is between the Earth and the Sun, blocking sunlight from reaching it. As the Moon orbits the Earth, different fractions of its illuminated surface become visible, creating various phases such as waxing crescent, first quarter, waxing gibbous, full moon, waning gibbous, last quarter, and waning crescent.
date = the date for which to calculate the moon phase
latitude = geographic latitude of the location
longitude = geographic longitude of the location
The calculation involves determining the Moon’s position in its orbit and comparing it to the positions of the Earth and Sun. This can be done using astronomical algorithms that take into account the gravitational influences on the Moon’s motion.
