New Moon
the lunar phase in which the moon is located between the sun and the earth. The moon at the time is invisible to an observer on the earth since the lunar hemisphere facing the earth is not illuminated (see). If during a new moon the moon is located precisely on the line joining the earth and the sun, then a solar eclipse occurs. The new moon is considered to mark the beginning of the month in a number of lunar calendars.
