Why Does Alaska Have Daylight Savings Time?

Last night, a few colleagues and I had dinner together, then went to watch the local fireworks, which didn’t start until midnight. When they started, it was after sunset, but it was still light enough to easily distinguish different colors. I’ve always liked the Muslim definitions of dawn and sunset – being able to distinguish a white thread from a black one – for their practicality; although technically, this would be dusk, not sunset. (While researching this simple assertion I discovered the difference between sunset and dusk – and that there are three different definitions of dusk. Further reasons for respecting Islamic pragmatism.)

I had only been in Alaska for a day before I started questioning the usefulness of Daylight Savings Time in Alaska. If there’s only about five hours’ difference between sunset and sunrise, and as far as I can tell, only about an hour or two of anything close to real darkness, where are the energy savings and public safety benefits that so many proponents of DST claim? I confess that I am not a fan of DST. I have a simple solution for those that say they like having more daylight in the summer – go to bed earlier and get up earlier. But I expect this solution, which I have implemented myself so simply, is as at odds with public sentimentality as is my opposition to using the word “gender” as a polite reference to the word “sex”.

It turns out that I am not alone. Hawai’i, Arizona, Puerto Rico and parts of Indiana refuse to use DST, and there is a movement to get it abolished in Alaska as well. The explanation for using both a single time zone in Alaska and DST seems to be a political expediency.

I had a lot of trouble getting here. My travel plans called for departing home in Kansas City on Sunday around 11:00 AM and getting to Anchorage about midnight (plus a three hour time change); going Kansas City – Dallas/Fort Worth – San Francisco – Anchorage. But when my first leg arrived at the DFW area, severe weather kept us from landing, and we had to divert to Oklahoma City for fuel. There were no gates available, so we spent about three hours on the tarmac waiting for more fuel, clearance to proceed to DFW, and a new flight plan. By the time I got to Dallas, it was too late to proceed and I had to spend the night there. On Monday I tried again, going DFW – Denver – Seattle – Anchorage, so it was no great surprise that only one of my bags arrived. The missing bag contained all my test equipment. By coincidence, my fellow engineer, who had used a different airline and was coming from San Diego, also lost his bag containing test equipment, but at least he got here on time. Both of our bags showed up a day after we arrived.

    Get your handy dandy sunrise/sunset and civil, nautical, and astronomical twilight charts at http://aa.usno.navy.mil/data/docs/RS_OneYear.html

    Includes the option to search by place name or lat-long. There’s another link there if you just want the data for a single day.

    The only drawback is that it doesn’t adjust for DST — it just gives the times in local standard time for the whole year. So for half the year you have to remember to adjust it.
