よくある質問
How are sunrise and sunset calculated?
The calculator uses a simplified solar position algorithm based on the equation of time and the solar declination for the given date and location.
What time zone are the results in?
Results are shown in UTC. You need to add your local UTC offset to get local time. For example, Moscow is UTC+3.
Why does sunrise/sunset time vary by location?
The times depend on latitude (how far north or south you are) and longitude (your east-west position, which determines your offset from UTC).
What happens near the poles?
Near the poles, there can be polar day (sun never sets) or polar night (sun never rises) during certain seasons. The calculator will indicate these cases.
What is solar noon?
Solar noon is the moment when the sun reaches its highest point in the sky for that location and date. It is the midpoint between sunrise and sunset.
