How Time Zone Conversion Works
Time zone conversion works by comparing the UTC offset of one location to another. Every city or region is measured relative to Coordinated Universal Time (UTC), which acts as the global reference point for civil time.
For example, Pacific Time is typically three hours behind Eastern Time, so a meeting at 9:00 AM in Los Angeles would be 12:00 PM in New York. The exact abbreviation may change during daylight saving time, but the relative difference between the two zones often stays the same.
TimeAtlas uses modern browser time zone data to help you compare cities accurately, reduce scheduling confusion, and quickly understand time differences for meetings, travel, and remote collaboration.
