If you ever need a map of time zones, here is a good map that not only gives the different zones but also the time and date in each zone.  It’s especially good for those who are traveling to Hawaii.  It’s been a while since we went to Hawaii with our family after our daughter graduated from high school, but I can remember trying to figure out the time difference.  For example, looking at this map I can see that Hawaii is five hours behind us here in Central Mountain Time.  I’m a visual learner, so it helps me remember to look at an actual map.
