World Clock

The World Clock shows the current local time in several time zones at once, updating live so you can see at a glance what time it is in different cities around the globe. You add the locations you care about, such as New York, London, and Tokyo, and the tool displays each one's current time side by side, usually with the date and an indication of day or night.

It works by reading your device's clock as a single moment in universal time and then applying each selected zone's offset and daylight-saving rules to render the correct local time. Because it relies on the IANA time zone database conventions, it accounts for places that observe daylight saving and those that do not, so the displayed times stay correct across seasonal transitions.

Remote teams, frequent travelers, and anyone with friends or family abroad use a world clock to avoid calling someone in the middle of their night and to coordinate live events across regions. It is also useful for tracking market hours, scheduling support coverage, and planning international calls. For finding a time that works for everyone, the Meeting Planner builds directly on this concept.

A good practice is to add the specific cities of the people you work with rather than relying on broad zone names, since offsets vary within a country. When you need to schedule a future event rather than just read the current time, pair the World Clock with the Meeting Planner to spot overlapping working hours, and use the Time Format Converter if some colleagues prefer 24-hour notation.
