Time Zone Converter - Global Meeting Scheduler
Schedule meetings across time zones without the headache. This converter shows the current time anywhere in the world, plus the best overlap for meetings. Includes DST adjustments and major cities.
How Time Zones Work
The world is divided into 24 time zones, each roughly 15 degrees of longitude wide. Most zones are offset by whole hours from UTC (Coordinated Universal Time), but some use 30- or 45-minute offsets (India, Nepal, parts of Australia).
US Time Zones
| Zone | UTC Offset | Common Cities |
|---|---|---|
| Eastern (ET) | UTC-5 / UTC-4 DST | New York, Miami, Atlanta |
| Central (CT) | UTC-6 / UTC-5 DST | Chicago, Dallas, Houston |
| Mountain (MT) | UTC-7 / UTC-6 DST | Denver, Phoenix (no DST), Salt Lake City |
| Pacific (PT) | UTC-8 / UTC-7 DST | Los Angeles, Seattle, Portland |
| Alaska (AKT) | UTC-9 / UTC-8 DST | Anchorage, Fairbanks |
| Hawaii (HST) | UTC-10 (no DST) | Honolulu |

Frequently Asked Questions
How do I convert EST to PST?
Subtract 3 hours. 9am EST = 6am PST.
What is UTC?
Coordinated Universal Time - the global time standard. All time zones are expressed as offsets from UTC.
Does Arizona observe daylight saving time?
No - most of Arizona stays on Mountain Standard Time year-round.
How do I schedule a meeting across 3 time zones?
Find the overlap of normal working hours (9am-5pm) in all zones. Tools like this converter help identify viable windows.
Why does India use a 30-minute offset?
India selected a single time zone for the entire country, splitting the difference between east and west.
What is the International Date Line?
An imaginary line through the Pacific where the calendar date changes. Crossing it eastward means subtracting a day.
