    Daylight Savings Time Fall 2017

    It’s the time of the year again to deal with Daylight Savings Time. Twice a year the country, and much of the world, moves their clocks forward one hour in the spring and back one hour in the fall. So on November 5th, almost everyone will move their clocks back one hour. All of the US will do that except the two states that don’t observe Daylight Savings time (DST), which are Arizona and Hawaii.

    Since I live in Arizona and have international clients, it is very important to me. I call the two changes in the year my Transitions Weeks. During the summer, AZ is three hours earlier than the east coast. During the winter, AZ is only 2 hours from the east coast. So I need to think a couple of weeks in advance when I’m scheduling my clients. Is this appointment after November 5th or before it? Otherwise I’ll be one hour off in my schedule.

    Tricky concept . . . Time. Daylight Savings Time is even trickier because it involved time and space. It is the place where space and time meet. There are 24 time zones in the world and they all have cryptic abbreviations, like CEDT or Central European Daylight Time. So it’s quite confusing, actually. The time zones start in Greenwich England, which is called GMT or Greenwich Mean Time. The time zones start there because that location is at 0 degrees longitude.

    If you live in the US, there are only four main time zones to be familiar with to feel comfortable with DST. Those time zones are: Eastern Time (ET), Central Time (CT), Mountain Time (MT) and Pacific Time (PT). When it’s Daylight Standard Time (DST), during the winter, the abbreviations are: EST, CST, MST and PST. They would be called: Eastern Standard Time, Central Standard Time, Mountain Standard Time or Pacific Standard Time.

    When it is during Daylight Savings Time (DT) in the summer, the abbreviations are: EDT, CDT, MDT or PDT. They would be called: Eastern Daylight Time, Central Daylight Time, Mountain Daylight Time or Pacific Daylight Time. The whole concept is easier when you are familiar with the abbreviations.

    So now when you move your clocks back one hour on November 5th, you will feel more connected. It is a collective experience -- except for me.
