Sunrise, Sunset, and Twilight! What are your city's times for today? (daily, European)

[EricS39]

So now play the winter point game and the summer game

Maximize points where you live

Calculate score by taking

200 +- sunrise score +-sunset score and then check your solar noon on the one you pick to see if you don't lose 100 additional points.


Winter game:
Everyone starts out with 200 free points
In winter:
Getting sunrise to occur before 8AM: Gain 50 more points
Otherwise Gain 0 more points

Sunset to occur after 5pm: Lose no points
Sunset to occur between 4pm and 5pm: Lose 40 points
Sunset to occur between 3pm and 4pm: Lose 70 points
Sunset to occur before 3pm: Lose 140 points

Solar noon more than 2 hours before/after clock noon: Lose an additional 100 points

Using a half-hour increment for a timezone, lose 200 points additional


Summer game:

For summer the idea is to reward points for every extra evening hour of daylight, and start penalizing for each hour after 6AM that the sun rises

Here's the summer game
Everyone starts with 200 free points

Sunrise before 6AM: No gain/loss in points
Sunrise 6AM to 7AM: Lose 30 points
Sunrise after 7AM: Lose 100 points

Sunset earlier than 7pm: Lose 50 points
Sunset 7pm to 8pm: No change in points
Sunset 8pm to 9pm: Gain 50 points
Sunset after 9pm: Gain 80 points

Solar noon more than 3 hours after clock noon: Lose 100 points
Half-hour increment timezone: Lose 200 points

My totals are 130 and 280.

Solar noon is 1.5 hours. (Sometimes 1 hour 48 minutes). Basically no one on here will have more than 3 hours.

[EricS39]

Yup you are in the right timezones

[Mac15]

Yea.

But on boundary. We could go back to gmt -1 but as I said 8:30pm sunsets!

Indonesia (Equator)

Pekanbaru (my place)

Summer (21st june because i live about half a degree north of the equator)

If I use GMT+7

Sunrise - 30, Sunset -50, solar noon 0, timezone 0 ---> -80 + 200 or 120

If I use GMT+6.30 (maybe it's more suitable, but not official)

Sunrise 0, Sunset -50. timezone -200, solar noon 0 ---> -250 + 200 or -50

Winter (21st Dec)

GMT+7

Sunrise 50, sunset 0, solar noon 0, ---> +50 + 200 + 250

GMT+6.5

Sunrise 50 Sunset 0 +250 - 200 (TZone) or 50

That's why we need DST

Actually the real question is

Why is the standard American work day ...9 to 5?

Why isn't it 8 to 4?

If the standard work day were 8 to 4 and in winter everyone just moves it to 9 to get the light in their eyes, we can do that instead of change the clocks

I guess the average person needs a fixed time so we need to have it done by changing the time itself

But how fascinating is it that though we push solar noon an hour ahead, the middle of an 8-hour standard work day is in fact solar noon in summer. Not completely but approximately so, your shadow is similar length when you walk into the office from when you leave the office end of the work day, if your work hours are standard.
