Live Sunset/Sunrise Countdown

A live, real-time countdown to the next sunrise or sunset at your location.

A static sunset time — "sunset today is at 7:42pm" — is useful information, but it's a different kind of useful than a live, continuously running countdown to that same moment, the same way knowing a flight departs at 3pm is different from watching the actual minutes tick down while you're sitting at the gate. The live version keeps the approaching moment present in a way a fixed time you glance at once doesn't.

This tool builds on the same solar position calculation used by the Sunrise & Sunset Calculator, but instead of just reporting both times, it automatically figures out which one is coming up next — sunrise or sunset — based on the current moment, and then counts down to it live, second by second, updating continuously rather than requiring you to keep checking a static number.

Enter your location's latitude and longitude, and the tool determines whether sunrise or sunset is the next event today, or rolls over to tomorrow's sunrise if both have already passed. It's a more immediate, ongoing companion to the standalone Sunrise & Sunset Calculator, built for someone who wants to watch the countdown in real time — waiting for golden hour, timing an outdoor event, or just tracking daylight as it happens.

1. Enter your location's latitude and longitude.
