How to Sign "Night" in American Sign Language (ASL)

In ASL, you make the sign for "night" by closing your fingers while moving your hand down from above your head to your face. The motion looks like the sun going down and darkness covering the world, making it easy for people to understand what the sign means. You can change the sign a bit to show different times at night. This simple and clear sign works well in any situation, and new learners usually pick it up fast because it makes so much sense.
