What is the astronomical New Moon?
The astronomical New Moon, or the invisible New Moon, is the moment when the moon is almost directly between the earth and the sun. At this moment the moon’s dark surface faces the earth. Therefore it is completely invisible even if it occurs in the middle of the night. The Astronomical New Moon occurs every 29 days, 12 hours, 44 minutes, and 2.8 seconds. The date and time of this invisible New Moon is commonly found in almanacs, newspapers and calendars.
