On 9th August it will your day with 2 astronomical dusk times, 00:04 and 23:59

Right now for you it's safe to say you get a nice twilight that runs through most of the 21:00 to 22:00 period (9pm to 10pm hour) then it's pretty dark after 10 unless the sky is clear visibility you can see some glow till half past 10


On the summer solstice, June 21st, you will get sunrise 4:56 and sunset 21:59

Civil twilight: Ending 22:52

Nautical twilight: Ends 0:29 (29 minutes past midnight)

Never completely dark

But unless the skies are completely clear of clouds, you will probably say it's pretty dark looking 10 minutes before midnight-ish on your longest day of the year


On your shortest day of the year, it would look pretty dark by no later than 17:30 (5:30pm) and sunset an early 16:07 ish

Even in winter when days are short and gloomy, your latitude allows you more twilight time than US locations with early winter sunsets. This can be quite nice.

Mac15 gets to see lingering light all night long on the summer solstice... For

The East Frisian it's safe to say there's a solid 2-3 hours of dark sky on June 21st

That's the difference between 53ish latitude degrees versus 55ish degrees north

Note:
Part of the astronomical twilight phase will still give the visual appearance of a night sky and only reflects visibility of star navigation using a telescope. So I consider pitched black starts way before 18 degrees below horizon.
