How Does the World Clock Work?

The world clock on this page shows the current local time for any city you add. Here's how to use it:

  1. Type a city name in the search box.
  2. Select the city from the list.
  3. The city card shows the current time, date, and GMT offset.
  4. Add as many cities as you need.
  5. Drag cards to reorder them however you like.

Your cities are saved in your browser. Come back later and they'll still be there.

How Many Time Zones Are There?

You might think there are 24 time zones, one for each hour of the day. But it's more than that. Some countries use 30-minute or even 45-minute offsets. India, for example, is GMT+5:30. Nepal is GMT+5:45.

In total, there are more than 30 unique GMT offsets used around the world. That's why a world clock tool is helpful. It handles all the offsets for you so you don't have to do the math.

What Is GMT and Why Does It Matter?

GMT stands for Greenwich Mean Time. It's the baseline that all time zones are measured from. When you see "GMT+3" or "GMT-5," that tells you how many hours ahead or behind a city is.

You might also see UTC (Coordinated Universal Time). GMT and UTC show the same time. UTC is the technical standard used in aviation and computing, while GMT is the more common everyday term. This world clock uses GMT offsets.

Knowing a city's GMT offset helps you figure out time differences fast. If you're in New York (GMT-5) and calling London (GMT+0), you know London is 5 hours ahead.

What Is Daylight Saving Time and How Does It Affect Time Zones?

Daylight Saving Time (DST) shifts clocks forward by one hour in spring and back in fall. Not every country does this. Japan, China, India, and most of Africa skip it entirely.

DST can make time zone math tricky. The US East Coast is normally GMT-5, but during DST it becomes GMT-4. Meanwhile, countries that don't observe DST stay the same year round.

This world clock handles DST changes for you. It always shows the correct current time based on each city's local rules.

How Can I Use the World Clock for Remote Work?

Working across time zones is one of the biggest challenges for remote teams. Here are some ways this tool helps:

The drag and drop feature lets you arrange cities in the order that makes sense for your day.
