Why this exists

I wanted a simple way to compare a handful of time zones at a glance, and to relate them back to whatever time it is where I am. No ads, no sign-up, no cookies.

Conversions come from your own device's time zone database, so daylight saving is always current. Sunrise, sunset and the sky colours are computed from each city's latitude and longitude rather than fetched, and the page caches itself, so it keeps working with no connection. Only the weather (from Open-Meteo), the visit counter and anonymous visit statistics (Cloudflare Web Analytics, no cookies) come from other sites. MIT licensed.

How to use it

See every city at once: the tiles at the top show each city's time and how far it is from you, coloured by its sky. Tap one to jump to its card.
Reorder cities: press and hold a city's ☆, then drag it up or down. Or tap Reorder and use ▲ ▼.
Set your base city: tap its ☆. The clock and slider follow that city.
Pick a time: drag across the hours, or tap the time and type one, like 3pm or 15:30.
Rename a city: tap its name and type a new one, like “Mom” or “HQ”. Clear it to get the city name back.
Add or remove: start typing a city or country and pick from the list; tap × to remove one.
Share: tap Share (Copy link on a computer) to send this exact view with its times, or Copy times for text only.
Clock and weather: use 12h / 24h and °C / °F under the cities. The weather is the forecast for the hour you are looking at.
Clock changes: an orange note appears when a city changes its clocks for daylight saving in the week before or the two weeks after the date shown.
Keep it on your phone: add it to your home screen. It works offline.
On a Mac: the free Time Zones menu bar app keeps your cities next to the clock.
