It was never a night object

Why Can You See the Moon in Daytime?

The Moon is up during the day about as often as at night; daylight just usually outshines it.

What people assume The Moon comes out atnightWhat happens It is up in daylightjust as often
The Moon keeps its own schedule, not the Sun's.
  1. Step 1 of 5

    The Moon does not wait for darkness.

    1 The Moon riseswhen it rises2 About 50minutes laterdaily3 Often while theSun is still up

    It rises and sets on its own timetable, drifting about fifty minutes later each day, quite independently of when the Sun is up.

  2. Step 2 of 5

    Seeing it is a contest against the sky.

    Bright gibbous Moon Easily beats the blueskyThin crescent Usually lost in theglare

    The daytime sky is bright blue, so the Moon is visible only when it reflects enough sunlight to stand out against that glare.

  3. Step 3 of 5

    The phase decides your chances.

    Full Moonup all night,never in dayHalf Moonhigh in theafternoon ormorningNew Moonup in daytimebut unlit

    A full Moon rises as the Sun sets, so it is a night object. A half Moon is high in broad daylight, which is when it is easiest to spot.

  4. Step 4 of 5

    A new Moon is up in daylight but invisible.

    It is above thehorizonIts lit sidefaces awaySo you seenothing

    At new Moon it sits almost in line with the Sun, so it is in the daytime sky with its dark side facing us and lost in glare besides.

  5. Step 5 of 5

    Looking away from the Sun helps most.

    Near the Sunhopeless glareHalfway across the skyoften visibleOpposite the Suneasiest, butthat is night

    The sky is darkest well away from the Sun, so a daytime Moon shows up best when it is high and the Sun is low behind you.

    The Moon rises about 50 minutes later each day, so it drifts through every combination of daylight and darkness each month.

The short version

The Moon is above the horizon in daytime about as often as at night, and you see it whenever it outshines the bright blue sky.

Try it yourself

Look for the Moon in the afternoon in the week after a full Moon. A fat half Moon is often obvious high in a blue sky.
