    Doesn't darken till midnight and starts brightening after 2am. Best time of the year!

    The still kinda bright in the sky at midnight is something that only lasts a week or two, so it seems.

    There's a noticeable difference between the north and south ends of the country. They are at 55 and 52 degrees latitude. The arctic circle is at 66.5 degrees. 66.5 - 55 = 11.5 degrees. At summer solstice, the sun only goes 11.5 degrees below the horizon in the north end of the country. 66.5 - 52 = 14.5 degrees for the south end. So the sun goes 14.5 degrees below horizon down there. So for the north of the country at solstice, it only gets as dark as nautical twilight, where horizon and vague outlines of objects can be seen.
    You have to be out and about at 1 or 2am to really appreciate it.

    I lived many years on a North Sea island. They used to advertise by showing pictures of golf games at midnight.

    Between that and frequent displays by the "Merrie Dancers".....

    Earth is tilted at max 23(.5)o in the Northern Hemisphere, hence summer time.

    It's the favourite time of the year for the the '23rdians' & the discordians.

    23 is a lovely prime number. Each parent contributes 23 chromosomes to the start of human life. The nuclei of cells in human bodies have 46 chromosomes made out of 23 pairs. Egg and sperm cells in humans have 23 chromosomes which fuse and divide to create an embryo. It takes 23 seconds for blood to circulate throughout the entire body. The human physical bior-hythm is 23 days. The Knights Templar had 23 Grand Masters. etc etc.
