About This Map
This map shows the boundary between day and night on Earth. The dark area represents night, while the light area represents day.
The curved line you see is called the "terminator" - it's where the sun is either rising or setting.
Use the date picker to see the day/night boundary for any date at the current time, or leave it set to today for real-time updates.
Due to Earth's axial tilt of 23.4°, the length of day and night varies throughout the year, creating our seasons.
