Some people expect to see the Sun during the day, and the Moon in the darkness of the night. But, depending on the position the Moon has reached in its orbit round the World, the Moon may appear during the day. Once the Sun is shining brightly, the Moon is less, if not impossible to see, because of the brightness of the daylight. Early dawn or twilight, when the sky is not too bright is the best time to see that the Moon, in all its phases, can appear during the day.
