TimeAtlas: Time Zone Converter

Compare time zones instantly. Scrub through a 24-hour timeline, see sunrise and sunset for every city, and keep your world clock organized with drag-and-drop simplicity.

TimeAtlas makes it effortless to see what time it is anywhere in the world — right now or hours from now.

Add cities from around the globe and watch their clocks tick in real time, side by side. Each city card shows the current time, how far ahead or behind it is from you, and whether it's today, tomorrow, or yesterday there. A sunrise or sunset icon tells you at a glance whether the sun is up, going down, or long gone — calculated from real astronomical data, not rough estimates.

The interactive timeline at the bottom is the heart of the app. Drag it forward or back to explore what time it will be across all your saved cities at any moment in the next 24 hours. Planning a call across three continents? Slide the timeline until the hours line up, and you'll see every city update instantly.
