Question

I saw a full moon on day 1 of the month when can i see the next full moon?

Answer 1

The position of the moon changes every 15 days.
In a month we can see i new moon and one full moon.
So another full moon can be seen after 1 month.

Answer 2

Moon is the only natural satellite which rotates around the earth is an elliptical orbit.

Full moon is a lunar phrase where the full circular moon appears in sky,with a brightly illuminated moonlight .

The normal gap between two full moons are generally 30 days .

So if we see a full moon on the 1st date of a month we will see the next full moon on the 31st of that month(if the month has 31 days) or on the 1st date of the next month (if the month has 30 days) or on the 2nd of the next month (if the month is February of a leap year) or on the 3rd of the next month (if the month is February of a normal year)
