  • Cumberland Parkway Time Zone Crossing

    Time Zone crossings in the United States generally happen at state borders which of course are easily recognizable landmarks. So you simply cross the state line and you change your watch. No big deal. Unfortunately Time Zones cut right through the middle of some states, like Kentucky. That can be a real inconvenience if you…

  • Indiana Toll Road Time Zone Crossing

    So you’re sitting somewhere outside of Chicago, Illinois cruising along the Indiana Toll Road. Most people know that Chicago and all of its nearby Indiana suburbs follow Central Time. On the other hand, much of the rest of Indiana follows Eastern Time. You just want to know when to change your watch, right? Let’s cut…

  • Southern Hills, Day 1 (Positioning)

    I returned to more familiar travel patterns during the current and hopefully permanent lull in the COVID-19 pandemic. This included my first airline flight since February 2020 when I returned from Bermuda. Then the world shut down and I endured the longest period of my life without an airline flight since I was fourteen years…

  • Florida I-10 Time Zone Crossing

    I’ll bet you’re checking your phone right now, driving along Interstate 10 in Florida and wondering where the time changes. I think I can help you. It happens between Mile Markers 160 and 161. If you’re driving westbound, going from Eastern Time into Central Time, set your coordinates to: 30.633557°, -84.904119° If you’re driving eastbound,…

  • Time Zone Dams

    Time continued to play on my mind. This time it came courtesy of a random search engine query that landed on 12MC for some unknown reason. However, the notion implied by this wayward message intrigued me much more than the average query. I’ve focused on structures split by borders before although this one had an…

  • Interstate Highway Time Zone Crossings

    I’ve noticed a lot of search engine queries lately seeking additional information about points along US Interstate Highways where travelers cross from one time zone into another. I’m going to do that myself soon on my upcoming trip and I couldn’t find a comprehensive resource either. Maybe there’s one out there hidden away in a…

  • Time Zone Boundary Craziness

    Please forgive me for another Time Zone article. I actually had another topic in mind so I’ll bump that one to make room for an unusual observation. Loyal reader David Overton commented on Making the Switch that the most recent Indiana time zone adjustment exacerbated an odd situation. Drivers traveling along a single 19 mile…

  • Making the Switch

    I learn the most amazing things as I delve into topics. For instance, thanks to Kansas Mountain Time, I now know how to change an area from one time zone to another should the need ever arise. The simplicity actually surprised me. It seemed much easier and less bureaucratic than I would ever imagine. Let’s…

  • Time Zone Limits, Part 2

    I went through a bit of an exercise to uncover the extreme eastern and western longitudes for each of the time zones in the Lower-48 United States, in Part 1. These points looked rather striking when I placed them in a map. Now, let’s look a little closer at the eight points individually. I consider…
