Swiftly Flow the Days

9 10 2018


A few of you in my peanut gallery have plonked this in my inbox, figuring it was relevant to me, and wanting to know my opinion.

I already wrote about it back on September 18 in my Minds feed, but I’ll cut and paste here.


Germany and the entire EU does clock changing on the last Sunday in March and the last Sunday in October.

What this means is that we’ll be falling back the last Sunday of this October, then springing ahead the last Sunday next March for sure. If Germany sticks with daylight time, then no more changing the clocks, if standard time, then fall back the following October then stay there.

As an aside, I’m sure that clock changing days are really hectic along the Clock Route in the Black Forest.

Cologne is slightly misplaced in time zone, it is slightly west of 7.5 degrees East (6.95 E) which indicates it should be in the UTC+0 zone (England) but is really, like all of Germany, in the UTC+1 zone (Central European), a zone which, BTW, is way too big and way too overextended. For instance, France, virtually all of which is in UTC+1, should be in UTC+0, because virtually if not actually all of it is west of 7.5 degrees East. Spain is the same way, though in its case, it’s definitely entirely west of 7.5 E.

What this means for Cologne is this:

Compared to St. Louis, Cologne is much further north in latitude, and much further west compared to the baseline longitude of its time zone, and that baseline is 15 E for the UTC+1 zone. St. Louis is close to its time zone’s natural baseline (90 W for UTC-6).

What this means is that, compared to St. Louis, Cologne’s latest summer sunset is very late, but the tradeoff is that its latest winter sunrise is also very late.

Latest Winter Sunrise

Cologne: 8:35 am
St. Louis: 7:19 am

Earliest Winter Sunset

Cologne: 4:26 pm
St. Louis: 4:39 pm

Earliest Summer Sunrise

Cologne: 5:18 am
St. Louis: 5:36 am

Latest Summer Sunset

Cologne: 9:50 pm
St. Louis: 8:29 pm

Which means if Germany sticks with daylight time, the latest winter sunrise will be 9:35 am. However, if it sticks with standard, earliest summer sunrise will be 4:18 am.

During the summer voyage, we got as far north as Hamburg, and there, the effect is even more pronounced. 4:50 am summer sunrise, 9:54 pm summer sunset, 8:37 am winter sunrise, 4:00 pm winter sunset. So if Germany sticks with daylight, the winter sunrise will be 9:37 am, but if it stays with standard, the summer sunrise will be 3:50 am.

Another problem is that the EU is not requiring all member states to come to the same decision of either standard or daylight, all it’s doing is requiring the end of switching. Meaning that in the same literal time zone, one country could be ahead or behind another.

Recommendation: EU should make France, Spain and Benelux countries switch to UTC+0 which is more natural zone, then make either daylight or standard a choice that all member states should make in the collective.
