How it works

The day–night line (terminator)

The curved line between light and dark is the terminator — the moving boundary where the Sun is rising or setting. Earth is always exactly half lit; the terminator sweeps westward at about 1,600 km/h at the equator as the planet rotates.

The point where the Sun is directly overhead (the subsolar point) tracks the seasons: it sits on the equator at the equinoxes, reaches the Tropic of Cancer (23.5°N) at the June solstice, and the Tropic of Capricorn (23.5°S) at the December solstice. That is why polar regions get 24-hour daylight or 24-hour night near the solstices.

Positions here are computed from the Sun's declination and the equation of time (NOAA solar algorithm). They show the geometric horizon; civil twilight keeps the sky bright for roughly 30 minutes past the line.

Frequently asked questions

Where is it daytime right now?
Right now (09:49 UTC) the Sun is directly overhead near 23.4°N 32.7°E. Every place on the lit half of the map — within about 90° of that point — is in daylight.
What is the day–night line called?
The terminator. It is the great circle that divides the daylit hemisphere from the night hemisphere, and it continuously moves as Earth rotates.
Why is one pole fully lit and the other fully dark?
Because Earth is tilted 23.5°. Near a solstice the Sun is overhead in one hemisphere, so its pole has 24-hour daylight (midnight sun) while the opposite pole has 24-hour night (polar night).
How accurate is this map?
The terminator and subsolar point are computed from the Sun's declination and the equation of time and are accurate to within a fraction of a degree. The map shows the geometric day/night boundary; add ~30 minutes of civil twilight for usable light.
