Notes
This program helps anyone who needs to know the Moon's phase (age), distance, and position along the ecliptic on any date within several thousand years in the past or future.
The ecliptic longitude is measured from the vernal equinox along the ecliptic in the direction of the sun's apparent motion through the stars. The moon's ecliptic longitude is calculated as well as the corresponding zodiac constellation.
The ecliptic latitude is positive if north of the ecliptic and negative if south. The age of the Moon in days as well as its visual phase are given.
