How do you know if it is going to be a full moon?

Answer 1

When the side of the moon that faces Earth (the same side of the moon always faces Earth) is fully bathed in sunlight. The Moon experiences day and night cycles, but it takes 28 days for the moon to complete a day/night cycle because of the Moon's relatively slow spin (which is what keeps the same side of the Moon facing Earth).

Answer 2

A full moon happens when the sun, earth and moon are in a line so we see the moon fully illuminated by sunlight. The full moon rises at sunset and goes down at sunrise.

When the three are exactly in a line, there is a lunar eclipse, but usually they are not exactly lined up at the time of full moon so there is no eclipse.

Answer 3

That depends where in the sky you see it in the early evening.

Low in the west, right where the sun just set . . . . . it's a crescent.

Straight south in the early evening . . . . . it's a half-moon, called "First Quarter".

Rising in the east in the early evening . . . it's full, nearly full, or just past full.

Answer 4

Several options exist:

• Watch it night after night.
• Look it up somewhere.
• Determine the relative position of Moon and Sun. If the Moon is west of the Sun, it is waxing. If it is to the east, it is waning. If this seems confusing, go back to the first suggestion - watch the Moon, until you see the pattern.

Answer 5

Just about any calendar will have the moon phases on it.

Answer 6

If you can see the moon at all, then that is not the time of New Moon.

Technically, the phase "New Moon" is the point in the moon's cycle when none of it is visible from Earth.

Answer 7

It's not hard. The next full moon comes 29.53 days after the last one.
