US Time Zone Map

US time zone meeting planner

Pick the cities your attendees are in. Every hour of the day is listed in each city’s local time, and the hours that fall inside everyone’s working day are marked.

    Local time in each city for each hour of the day

    How the planner works

    Each row is one hour of your chosen date in the first city’s time zone. For that instant, every other city’s local time is read from your browser’s IANA time zone database, the same database your phone and calendar use. A row is marked as shared when the whole hour sits inside the working hours you set for every city.

    Worked example, Friday, October 30, 2026, 9:00 AM to 5:00 PM: New York is on EDT (UTC−4) and Los Angeles on PDT (UTC−7), three hours apart. Los Angeles starts work at 9:00 AM Pacific, which is 12:00 PM in New York, and New York stops at 5:00 PM, so the shared window is 12:00 to 5:00 PM Eastern: five hours. Add Honolulu (HST, UTC−10, no daylight saving) and only 3:00 to 5:00 PM Eastern remains, because Honolulu’s 9:00 AM is 3:00 PM in New York.

    Assumptions: everyone works the same hours in their own local time, and the date is a working day for all of them. Holidays and split shifts aren’t modelled; adjust the hours if a city keeps a different day.

    Frequently asked questions

    What is the best time for a meeting across all US time zones?

    For the four mainland zones with 9-to-5 hours, the shared window is 12:00 to 5:00 PM Eastern (9:00 AM to 2:00 PM Pacific). Adding Alaska shrinks it to 1:00 to 5:00 PM Eastern; adding Hawaii leaves only 3:00 to 5:00 PM Eastern while the mainland is on daylight time, and 2:00 to 5:00 PM in winter. The planner computes this for your exact date.

    Does the planner handle daylight saving time?

    Yes. Each hour is converted with your browser’s IANA time zone database for the date you pick, so a plan for a date after the November or March switch uses the new offsets, and zones that skip DST (Arizona, Hawaii) stay put.

    Why does Arizona’s overlap change during the year?

    Phoenix stays on Mountain Standard Time all year. In summer that matches Pacific Daylight Time; in winter it matches Denver. So a 9 AM Phoenix call is noon in New York in summer and 11 AM in winter.

    Can I share a plan?

    Yes. The address bar updates as you change cities, hours or the date. Copy the link (or press “Copy link”) and anyone who opens it sees the same plan, converted to the same cities.

    Is anything I enter sent to a server?

    No. The cities, hours and date are kept in the page address and computed in your browser. Nothing is stored or sent anywhere.
