Question

If you observe a Full Moon on Jan 12th, on what date would you observe the next New Moon? What date

Answer 1

Answer:

14.765 days

Explanation:

The Moon has 8 different phases that create an entire Cycle starting with a New Moon. The phases of this cycle are the following...

New Moon

Waxing Crescent

First Quarter

Waxing Gibbous

Full Moon

Waning Gibbous

Last Quarter

Waning Crescent

This entire cycle takes 29.531 days to complete the entire cycle and start with the New Moon phase again. Therefore since the Full Moon phase is halfway through the cycle we can divide the total time it takes for the cycle to complete by 2 to calculate the time between a New Moon and a Full Moon.

29.531 / 2 = 14.765 days
