The actual "new moon" is a moment, a point in time; it doesn't really have a duration. But for practical purposes, there is one day on which the Moon is generally not visible at all, and this is the day of the new moon. One day later, you will be able to see a thin crescent Moon - the one that some people call "Diana's Bow" - very low in the evening sky next to the setting Sun.
Most people aren't up and out in the hour before sunrise, but if you were to look up to the east just as dawn was breaking the day BEFORE the new moon, you would be able to see the crescent moon then, as well.
Roughly approximately about 29.531 days, which is 4.2187 weeks.
About 29.5 days.
After 21 days from a new moon, you would reach a full moon phase. The lunar cycle takes approximately 29.5 days to complete, so 21 days after a new moon would place you close to a full moon phase.
7 days
The cycle of the moon's phases runs 29.53 days.
That depends on what phase the moon is currently in. The moon goes through each phase once per 29.53 days.
Roughly approximately about 29.531 days, which is 4.2187 weeks.
About 29.5 days.
It takes about 29.5 days for the moon to go from one new moon phase to the next new moon phase.
After 21 days from a new moon, you would reach a full moon phase. The lunar cycle takes approximately 29.5 days to complete, so 21 days after a new moon would place you close to a full moon phase.
Only one. New moon is the phase where the sun is completely dark, and crescent is the phase where only a sliver (or crescent) is showing. The night after a new moon, part of the moon will be illuminated, and it will be a crescent.
1/2 of 29.53 days = 14.77 days (rounded)
first quarter
It takes about 7 days for the Moon to transition from a new moon phase to the first quarter moon phase.
One week from now, the moon will likely be in the first quarter phase, where half of the moon is illuminated. The new moon phase is followed by the waxing crescent phase and then the first quarter phase in the lunar cycle.
It takes about 29.5 days for the moon to complete one full phase cycle, from new moon to full moon and back to new moon again.
