The 16hour and 45minute Day in Amsterdam

June 21st, 2019.

Today is the longest day of the year in the northern hemisphere, and it got me thinking about how long the day is in Amsterdam versus Seattle. So let’s do some latitude math:
– Seattle is at 47°36′35″N
– Amsterdam is at 52°22′N
Calculating this shows me a difference in latitude of 529 km (328.705 miles).

Today, on June 21st, the day is 45 minutes longer in Amsterdam versus Seattle:
– In Seattle, sunrise is at 5:07am and sunset is at 21:10 (9:10pm) = 16 hours and 3 minutes
– In Amsterdam, sunrise is at 5:18am and sunset is at 22:06 (10:06pm) = 16 hours and 48 minutes

So there are some fun facts to ponder. Mostly I notice how light it still is at 10pm!

    Interesting. I should look up Richville, MN But, we are not having much sunshine anyway. The sun does come up way into North East. Have you looked up Wasila, AK?
