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.

Step 1 of 5
The Moon does not wait for darkness.
It rises and sets on its own timetable, drifting about fifty minutes later each day, quite independently of when the Sun is up.

Step 2 of 5
Seeing it is a contest against the sky.
The daytime sky is bright blue, so the Moon is visible only when it reflects enough sunlight to stand out against that glare.

The phase decides your chances.
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.

Step 4 of 5
A new Moon is up in daylight but invisible.
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.

Step 5 of 5
Looking away from the Sun helps most.
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.
