This amazing NASA video shows the hour-by-hour phases of the Moon for the entire year of 2019. But there's a lot more info as well:

Craters near the day/night line are labeled
The size changes as the Moon gets closer and farther from Earth in its elliptical orbit
The Moon appears to rotate a little left/right and up/down due to its orbital motion
The distance from the Earth to the Moon is displayed behind the big Moon display
The phases of Earth and Moon are shown together in the upper left
The points on the Moon directly under the Earth (blue dot) and Sun (yellow dot) are shown
All the numerical data is displayed as well
