How do you tell when it is sunrise and sunset?

Answer 1

Generally, if it is dark outside and it gets lighter, the Sun is rising. If it's bright outside and then it gets dark, that was sunset.

Officially, "sunrise" is when the upper limb of the Sun comes into view on the horizon, and "sunset" is when the upper limb of the Sun disappears behind the horizon.

Answer 2

Sunrise is when the sun first appears above the horizon in the morning, while sunset is when the sun disappears below the horizon in the evening. You can also use tools like a clock or calendar to determine the exact times for sunrise and sunset in your location.
