How to read the map
The line between day and night is called the terminator. Its shape changes with the seasons: around the June solstice the Arctic stays lit all day and Antarctica stays dark, and around the December solstice it's the reverse. At the March and September equinoxes the line runs almost straight from pole to pole, and day and night are close to equal everywhere.
The four shades of darkness show civil, nautical and astronomical twilight: the sun is 0–6°, 6–12° and 12–18° below the horizon. Deeper than 18° is full night.
The faint vertical lines are 15° apart, one for each hour of time difference from UTC. Real time zone borders follow countries rather than straight lines.
