Plan your day with accurate sunrise and sunset times. Our calculator uses astronomical algorithms to determine exact times for any location on Earth, any day of the year.
Sunrise and sunset times depend on your latitude, longitude, date, and local timezone. The sun's position changes throughout the year due to Earth's axial tilt and orbital position. Our calculator accounts for atmospheric refraction which bends light and makes the sun visible slightly before it actually rises above the horizon.
