Put the free morning light calculator on your own website. Your visitors enter a city and get a rule-of-thumb estimate of how long to go outside, from the clouds and the height of the sun.

Open the calculator as it appears in the frame

Good to know

No cookies and no tracking inside the frame. The calculator only sends the city search and a rounded location for the weather.
The code adds one text link, “Calculator by LightOtter”, below the frame, and the frame shows the same link. Please keep both.
The minutes are a rule of thumb, not a measurement and not medical advice.
Free to use. If you change the height, about 640 pixels shows the result without scrolling.

How the city search and the weather work is described in our privacy policy.
