Everything about today’s light, in one place.

Today opens on the next light and its countdown, the day’s columns, and the light windows still ahead. The whole screen takes on the color of the light that’s coming: warm before golden hour, blue before blue hour, night once the day’s light is done.

Drag the sky through the day.

The sky shows the sun’s height and the weather. It isn’t a compass.
