How to set the Moon Phase
• The moon phase represents the period from the time
when the last new moon occurred to noon of the
current day in day increments.
• The period between new moons is called a “synodic
month,” and its average length is approximately 29.5
days.
* Round off the number of moon phase to the nearest
whole number (Example: 7.8, 8, 24.2, 24)
* Refer to the weather report of your local newspaper
for current moon phase information.
