Road Trip Time Zone Calculator
Know What Time You’ll Arrive — Even When You Cross a Zone
Long drives across the US, Canada, or into Mexico often cross at least one time zone line, and it’s easy to lose track of exactly where. One minute you’re checking the clock in Central Time, and the next you’ve crossed into Mountain Time without realizing it, which can throw off arrival estimates, check-in times, and calls home. Our free Time Zone Calculator shows you exactly what time it’ll be at your destination, based on your actual departure time and the zones you’re crossing.

Driving across zones? Enter your departure time to see the local time on the other end and how far apart they are.
Not sure which zone a state or province is in?
WA, OR, CA, NV (most), western ID, most of BC
MT, WY, CO, UT, NM, eastern ID, most of AZ, AB, SK (most)
TX, OK, KS, NE, SD, ND (most), MN, IA, MO, AR, LA, WI, IL, MS, AL, TN, most of MI's UP, western KY, MB, most of Mexico
ME, NH, VT, MA, RI, CT, NY, NJ, PA, DE, MD, DC, VA, WV, NC, SC, GA, most of FL, OH, most of MI, most of IN, eastern KY, ON, QC
NB, NS, PE
Several states and provinces are split between two zones (parts of ID, KS, ND, SD, TX, MI, IN, KY and FL, among others) — if your route hugs a zone line, treat this as a starting point and confirm locally.
Converted time
Time zone offsets can shift with daylight saving rules, so double-check close to your travel date — especially if you're driving through Arizona or Saskatchewan, which don't observe DST, or crossing a zone right around a DST change.

How It Works
Enter your departure date and time, then choose your starting point and destination from our list of North American time zones. The calculator instantly shows the local time at both ends of your drive, along with how many hours apart they are. It automatically accounts for daylight saving time based on the exact date you enter, and handles the handful of places, like Arizona and Saskatchewan, that don’t observe DST at all. If you’re not sure which zone a state or province falls into, our built-in reference guide breaks it down for you, including the states that are split between two zones.
Why It’s Useful
Whether you’re timing a border crossing, coordinating a hotel check-in, or just don’t want to show up an hour early (or late) to a meeting, knowing the real time at your destination, not just the driving distance, helps you plan a trip that actually goes smoothly. It’s especially handy on longer North American drives, where crossing multiple zones in a single day is common.
Keep in mind that zone boundaries can be uneven and DST rules vary by region, so double-check locally if your route runs close to a zone line.
