03/12/2021 – Ephemeris – It’s about time

March 12, 2021 Comments off

This is Bob Moler with Ephemeris for Friday, March 12th. Today the Sun will be up for 11 hours and 45 minutes, setting at 6:45, and it will rise tomorrow at 6:58. The Moon, 1 day before new, will rise at 7:31 tomorrow morning.

Sunday morning at the instant the clock strikes 2 am, it will magically become 3 am. March 14th will become the shortest day of the year at 23 hours. The hour will be returned, without interest I might add, on the first Sunday in November. And we can’t even say “Spring forward.” It’s not even spring yet. “Late winter forward” just doesn’t have the same ring to it. Actually noon is not midday for those who work days. It’s more like two in the afternoon, maybe later. We have more leisure time after work than before, which kind of makes sense. But in summer the Sun’s out a long time anyway. In late June the Sun doesn’t set until 9:30 at night around here. It doesn’t get really dark until after 11 pm. It may be great for golfers, but not for those who enjoy the night sky.

The astronomical event times given are for the Traverse City/Interlochen area of Michigan. They may be different for your location.

The Persistence of Memory by Salvador Dalí.

Growing up in the 1950s I wasn’t aware that we in Michigan didn’t set our clocks forward or back with the seasons until we got a television. All of a sudden in April all the evening shows came on an hour earlier. Around Halloween, they went back to their former times. In the 60s the politicians started to mess around with our clocks, first on the Federal level, then the state level. Long story short, we’re doing the spring forward, fall back thing like almost everyone else. The problem I see is that we are far west of our Eastern Standard Time meridian of 75 degrees west longitude, which runs through Philadelphia, PA. I live 43 Earth rotational minutes west of there. Standard time for us is almost like Daylight Saving Time for New York City. So come Sunday we will experience double daylight time. Kinda like “Double Secret Probation.” /rant
