Each city is a small tile that reads its own moment. Here's what every part of it means:
LondonDSTGMT+1
03:42 AM
Mon, May 4
🌙
12345
1Background colour — paper at midday, gold at dawn, rust at dusk, deep navy at night. Tells you the city's moment without reading the clock.
2DST — the city is currently on daylight saving time, so its offset from UTC has shifted by an hour from its winter standard.
3GMT offset — hours ahead of (+) or behind (−) UTC right now. Adjusts automatically when the city flips DST.
4Live time + date — refreshes every ten seconds. The date matters when you're crossing midnight: 3 AM in London is still last night in New York.
5Sun, sunrise, sunset, or moon — at-a-glance read of where the city is in its day. ☀️ day · 🌅 dawn · 🌇 dusk · 🌙 night.
01Language
The language picker sits in the top-right of the tool's header. Switching it translates every label, formats time and date in the local convention, and renames cities to their native spelling. Your choice is preserved in the page's URL hash, so a link like #lang=ja opens in Japanese for whoever you share it with. Nine languages are supported: English, Español, Français, Italiano, Português, Deutsch, 日本語, 한국어, 中文.
02Quick Convert
Set a time in any one city. The others sync automatically. Add up to four cities so you can plan a meeting across NYC, LA, Tokyo, Dubai in one glance. Each row has an × to remove it; the "+ add city" button appears until you reach four.
If a converted time crosses midnight, you'll see a small +1d or −1d tag next to the city — that's the day shift.
03Add a city to your tracked list
Pick from the "Add a timezone…" dropdown. The city appears as a card below, showing the live time, date, and a sun/moon icon for whether it's day or night there.
04Remove a city
Hover (or tap on mobile) any tracked card and a small × appears in the top-right corner. Click it to remove.
05Your cities save
Whatever cities you add or remove are saved on this device automatically. Come back tomorrow on the same browser and your set is still there — no account, no login.

07The spotlight at the top
Those three live cities aren't fixed. They're places we're holding attention on right now — the moments worth knowing the time of, not just the time. The set refreshes as the world changes, not on a schedule.
