International calling guide
The United States spans six time zones from EST (UTC−5) on the East Coast to HST (UTC−10) in Hawaii, so always confirm your contact's state before dialling. The safest cross-country window is 12 PM–3 PM Eastern, which keeps you within business hours from New York all the way to Los Angeles.

Six time zones and wildly different work cultures make US calls easy to miss. These four factors cut through the complexity.
Pro tip: Schedule calls for 10–11 AM Eastern to hit a window where East Coast callers are settled in and West Coast callers are just arriving. Avoid Mondays before 10 AM and Fridays after 3 PM in any time zone.
The US spans EST (UTC−5), CST (UTC−6), MST (UTC−7), PST (UTC−8), AKST (UTC−9), and HST (UTC−10). Always confirm your contact's state — or even city — before dialling.
Most US states observe DST, shifting clocks forward in March and back in November. Arizona (except Navajo Nation) and Hawaii do not — factor this in when scheduling calls.
Finance and law firms on the East Coast start as early as 7 AM. Tech companies on the West Coast often don't hit stride until 10 AM. Match your timing to the industry, not just the clock.
Beyond federal holidays like Thanksgiving and Labor Day, many states observe additional holidays. Check both federal and state calendars for your contact's location.
The time differences range from 8 hours ahead of UTC to 5 hours behind UTC, showcasing the diverse time zones across the globe.
