How to Schedule Across US Time Zones
With the rise of remote work, scheduling meetings across the United States has become a daily challenge. Whether you're coordinating with a client in New York (EST) or a development team in California (PST), getting the time zone math wrong can lead to missed meetings and lost revenue.
Our free US Time Zone Converter instantly shows what time it is across the country. The quick overview map helps you avoid accidentally scheduling a 9 AM EST meeting for a coworker in Los Angeles — who'd have to wake up at 6 AM.
Worked Examples
- 9:00 AM PST → 12:00 PM EST (add 3 hours)
- 6:00 PM PST → 9:00 PM EST (add 3 hours, same day)
- 11:00 PM PST → 2:00 AM EST (Next Day) — this is where day-rollover matters: adding 3 hours pushes past midnight, so the East Coast time falls on the following calendar day
The Time Zone Gaps at a Glance
- Pacific to Mountain: 1 hour
- Pacific to Central: 2 hours
- Pacific to Eastern: 3 hours
- Eastern to Central: 1 hour
- Eastern to Mountain: 2 hours
These gaps hold steady year-round for the four contiguous US zones, since they all move into and out of Daylight Saving Time on the same dates. Arizona and Hawaii are the exceptions — see the FAQ below.
