The moon always rises and sets and is therefore always in the sky every day month in month out but we can not always see it. This is because moonrise and moonset happens at all different times depending upon its phase or position in relation to the sun and earth. At new moon it rises approximately with the sun and sets approx with the sun. We cannot see it but it is there all the same but its sunlit half is then sun facing. Take a look on the net and u will see all the differing moonrise and moonset times. It has nothing to do with certain times of the year but all to do with its monthly orbit of earth. Hope this helps.
