discussion Shortest Daylight hours..................

[Dave Ward]

Or longest daylight, depending whether you are in the Northern or Southern Hemisphere.
As a factlet - did you know the daylight hours in Singapore only vary by 10 minutes over the complete year ( 'cos it's nearly on the Equator ) ?

We had quite extreme daylight/night when we lived on the Outer Hebrides. In summer it was still light at 11.00 at night whereas in winter it only got daylight at 10.00 in the morning and was dark again by 3.00.

 

[Dave Ward]

Above the Arctic Circle or below the Antarctic, there's either 24 hours daylight, or 24 hours darkness at the solstices

My daughter lived in nearby Malaysia for a year once and it was the same there. I went to visit her twice at different times of year and there was no notifiable difference in daylight at all.

There's a noticeable difference between Buffalo, NY & Dayton, OH, just a couple hundred miles south.

During the Summer Solstice it doesn't get dark here in NW Montana till 9:00 PM.

I went for a pint after arriving late into Bodo, Norway one summer. Sitting on the pub decking enjoying the view and the low sun, I contemplated another beer and checked my watch - half twelve, time for another. Then I realised it was actually 00:30 and I had to be up early for work in 6 hours.

Hehehe … I was watching some YouTube videos of Americans on holiday in the UK some months ago, and they commented more than once on that it was still light fairly late in the evening in June — like 21:30 hours or so. To me, it being close to dark at 21:30 around the longest day of the year would be very strange

Yet the evenings will still close for a bit as the extra daylight comes in the morning by some quirk.

Changes by about three minutes a day at the fastest (During March, April, September, and October) I think Karl. For some reason the rate of change isn’t even either.
I just remember that when I still worked I would be going home in daylight by the second week in February.

Off on a slight tangent, but once whilst working 12 on 12 off just off Alaska, the I’m fairly sure the night shift saw more daylight than the day shift.

Yes, it's very predictable here that setting timers for night lights is seldom changed once done. Morning Glory's have enough time to close and open everyday and I don't rely on the clock so often. The only difference is the position of the sun every half of the year.

Beautiful flower Wabble .

Here at Race Towers the coming of the Winter solstice is seen as the reason to celebrate, more daylight and less of the dark dreary days of winter . Soon the seed catalogues will start to arrive , roll on spring .

I haven’t looked into it, but I expect it follows essentially a sine wave? This because of the change being caused by a tilted body moving in a circle, so intuitively that would result in the change gradually in- and decreasing.

Definitely sine wave (sigmoidal curve) when graphed out. The “tilted” parts obviously move in an elliptical path around the sun, with the path becoming more circular at the equator and more elliptical at the poles, but I suspect the rotational speed of the earth comes into it somewhere…..

When you look it up, can you also look up Focault’s pendulum, because I don’t quite get how that varies in rotational time depending upon latitude….fascinating device though….

Dave, I need a drink. Can I pour you one?

Nope, just pass the bottle!

Slightly along those lines - I met a flat-earther, in South Africa ( a genuine Boer! ), convinced that the earth was flat, no amount of argument could convince him otherwise - I was an officer in the MN at the time, and I just couldn't see how any sane person could believe this..............( having done several round- the-world trips ). What really floored me was his explanations for the sun rising/setting, and the need for an international date line. He spoke in English, but it might as well have been Klingon for all the sense I could make of it! I suppose drinking half a bottle of Oude Meester brandy didn't help!!

Sure we have cats to prove the earth is a globe, if it was flat they would of pushed everything off by now.........
