Why can you see the Moon during the day?

The short answer

Because the Moon is often above the horizon while the Sun is up, and it is bright enough to show through the daylight. It makes no light of its own: we see sunlight reflecting off its surface, by day as by night.¹ Stars are up there during the day too, but the sky is too bright for us to see them.¹ The daytime Moon can be seen on most days of the month, apart from those closest to the full Moon and the new Moon.²

What the evidence shows

It isn't really a night-time object

NASA scientist Sarah Noble points out that we think of the Moon as belonging to the night because books, films and weather symbols show it that way, when it spends almost as much time in the daytime sky as at night.¹

The Moon is above the horizon for about 12 hours a day, but those hours don't always line up with daylight.² At mid-latitudes in winter, shorter days leave less time to see it by day.²

The phase tells you when to look

The Sun always lights half of the Moon, and the cycle of phases repeats about every 29.5 days.³ Where the Moon is in that cycle sets when it rises and sets, and so whether it shares the sky with the Sun.³

When each phase is up, from NASA's Moon phases guide³
Phase	Rises	Sets
Waxing crescent	In the morning, after the Sun is up	At night, after the Sun is down
First quarter	Around midday	Around the middle of the night
Waxing gibbous	In the afternoon, before sunset	In the early hours, before sunrise
Full	At sunset	At sunrise
Waning gibbous	At night, after sunset	In the morning, after sunrise
Third quarter	Around the middle of the night	Around midday
Waning crescent	In the very early morning, before sunrise	In the afternoon, before sunset
New	With the Sun	With the Sun, and not visible in the daytime sky

Why it looks so pale

NASA describes the daytime Moon as often visible as a faint, pale presence.³ The light reaching you is the same reflected sunlight as at night,² now seen against a bright sky instead of a dark one.

Our take

This part is our own interpretation, not a sourced finding.

We like this question because the answer is mostly about us. The Moon's timetable has nothing to do with our day and night, so a daytime Moon isn't unusual. It only feels that way because we were taught to draw it next to the stars.

What we can't say for sure

The rise and set times above are the general pattern. Exact times change with your location and the date, so check local predictions if you want to plan a sighting.
