US Time Zones is a Chrome extension that helps you quickly check the current time anywhere in the United States without opening multiple websites or searching online. It displays the major US time zones—including Eastern, Central, Mountain, and Pacific Time—in a clean, easy-to-read interface directly from your browser toolbar.

The extension automatically shows your local time alongside popular US cities such as New York, Chicago, Denver, and Los Angeles. You can add additional cities from across the country, pin your favorites, remove locations you don't need, and create a personalized list that fits your daily workflow.
