The world is divided into 24 time zones, each roughly 15 degrees of longitude wide. UTC (Coordinated Universal Time) is the reference point — zones are expressed as offsets from UTC (e.g., EST is UTC-5, JST is UTC+9). Some regions use half-hour or 45-minute offsets.
This converter uses your browser's built-in time zone database, which accounts for daylight saving time (DST) automatically. Times are converted correctly whether DST is active or not in either zone.
UTC (Coordinated Universal Time) is the global time standard. It replaced GMT as the reference. UTC doesn't observe daylight saving time. All other time zones are defined as offsets from UTC.
Pick a time in your local zone, convert it to each participant's zone, and find a window that works for everyone. Business hours (9 AM - 5 PM) overlap varies — US East Coast and Europe have about 4-5 hours of overlap, while US and Asia have very little.
