Current time, date and weather — world clock and time zone tools

One place for time, sky and weather

Time & Sky answers the small questions that come up every day. What time is it in Tokyo right now? What's 3 PM Eastern in my time? When does the sun set tonight? Will it rain tomorrow? How long until New Year? Each tool does one job and loads fast, and none of them need an account. Times come from the time zone database built into your browser, weather comes from the Open-Meteo forecast models, and whatever you type stays on your own device.

Which tool do you need?

• "What time is it over there?" — the World Clock, live for any cities you choose.
• "What's 2 PM their time in my time?" — the Time Zone Converter, for any date, with daylight saving handled.
• "When can we all meet?" — the Meeting Planner, comparing working hours across up to five cities.
• "What's the weather there?" — the Weather page, with current conditions and a 7-day forecast for any city.
• "When is sunset? What's the moon doing?" — Sun & Moon, for any city and any date.
• "How long until…?" — the Countdown, shareable with a link.

Beyond the tools

The questions behind these tools are interesting in their own right, so we write about them too. The Guides section covers how time zones came to exist (railroads, mostly), why clocks jump twice a year, why the moon changes shape, how a forecast is made, how to beat jet lag and when the light is best for photos. Plain language, no textbook. If you've ever wanted to win the "why is China all one time zone?" argument at dinner, start there.
