Equinox Daylight

Track sunrise, sunset, and daylight hours for cities across the globe. See the solstices and equinoxes on a full year calendar.

Equinox Daylight is your personal sun tracker — a beautifully simple tool that tells you exactly how much daylight you get each day, wherever you are in the world.

Pick from five cities across the globe: New York, London, Tokyo, Sydney, and Reykjavik. The Today tab shows sunrise time, sunset time, and total daylight hours computed for your selected city using the precise latitude and the current day of the year. A clean visual bar shows how much of the day is lit, so you can feel the rhythm of the sun at a glance.

The Calendar tab gives you the full year view. See the four great solar events — Spring Equinox, Summer Solstice, Autumn Equinox, and Winter Solstice — plotted across the year, along with a monthly daylight comparison chart that shows how dramatically your daylight changes from winter to summer. At high latitudes like Reykjavik the swings are dramatic; near the equator they are gentle. The calendar makes it vivid.

The Cities tab lets you switch instantly between all five preset cities. Each city shows its latitude so you understand why Reykjavik has nearly 21 hours of daylight in June but less than four in December, while Sydney and Tokyo tell a very different story.

No ads. No account required. No internet connection needed. Everything works offline using an elegant astronomical approximation based on your latitude and the day of the year.
