Time Zone Converter & World Clock

The World Clock & Time Zone Converter is your all-in-one tool for comparing times across multiple cities worldwide. Here is how to use it: 1) Add cities: Click the "+" button above the timeline to search and add cities you want to compare. You can add as many cities as needed and remove them anytime. 2) Read the time bars: Each city displays a color-coded 24-hour bar. Green indicates working hours, yellow indicates possible weekend work, and gray indicates off hours. This gives you an instant overview of each city's availability. 3) Track current time: The blue vertical line marks the exact current moment across all cities. Glance down to see what time it is in every added city right now. 4) Compare times: Click and drag the blue time cursor to explore different moments. As you drag, all city times update in real-time, making it easy to find overlapping working hours or the best window for a call. 5) View details: Each city row shows its current local time, timezone abbreviation (e.g., EST, GMT), and UTC offset. When daylight saving time is active, a DST badge appears. A dedicated UTC time row below the local clock shows the current UTC reference time. Our database covers 39,000+ cities across 95 countries and 350 timezones via smart alias mapping.

Time zones are defined by their offset from UTC (Coordinated Universal Time). Each time zone covers roughly 15 degrees of longitude, with a one-hour difference between adjacent zones.

You can check the current local time in any major city worldwide using Global Time Now. Simply add cities to our interactive world clock to view real-time times across 200+ locations.

Use our meeting planner tool. Select participating cities, set your preferred time range, and our algorithm will recommend optimal meeting times that work across all time zones.
