There are actually nine time zones in the United States but for the purposes of where you and your furry friend are most likely to travel, you probably only need to be aware of the four mainland time zones, plus perhaps, Alaska. The time advances one hour for each time zone border you cross heading east. So, for example, if it is 8am in Alaska, it is 9am in California, 10am in Denver, 11am in Omaha and noon in New York. Remember to deduct one hour for each time zone into which you cross when starting on the east coast heading west.
