Plain English

Terms of use

A short, plain-English summary of the rules for using SunAndMoon. By using the site, you agree to the points below.

Using the site

SunAndMoon is a free tool for looking up sunrise, sunset, golden hour, blue hour and moon information for cities around the world. You can use it for personal, educational or commercial purposes at no cost.

Accuracy of times

Sunrise, sunset, golden hour, blue hour and moon times are calculated with the SunCalc astronomy library and are normally accurate to within about a minute for a clear, flat horizon. They are estimates, not guarantees, and can be affected by hills, tall buildings, weather and atmospheric conditions. Do not rely on these times alone for safety-critical decisions, such as aviation, maritime navigation or religious observance, without checking an authoritative local source.

Acceptable use

Please do not attempt to disrupt the site, scrape it at a rate that harms availability for other visitors, or use it for anything unlawful.

The site is provided as is, without warranties of any kind. We are not liable for losses arising from your use of the site or reliance on the times it shows.
