12hours _________________ June 21 is around the time of the solstice, not the equinox. This marks the beginning of winter in the Southern Hemisphere, and the beginning of summer in the north. How long the sun is up for any individual will depend on the individual's latitude. On this date an observer at the north pole is experiencing non-stop daylight, and an observer at the south pole is in the middle of the long winter night.
Even though we have the specific date, the answer still depends on the exact location
on the earth that you're interested in. The answer changes every 30 miles or so.
At the south pole, the sun didn't rise at all on September 15th. In fact, there hadn't been
a sunrise in the previous 85 days, and there wouldn't be one for another week.
It makes a big difference where you're talking about.
You need to give the exact location on earth that you are talking about.
Anywhere between 0 and 24 hour - it depends on your latitude.
The sun always goes 23.5 degrees north of the equator around June 21st. This line of latitude ics called the Tropic of Cancer.
Depending on where you live, anywhere between 23.5 degrees north of a point exactly west, and exactly north. If you are within the southern polar region, it won't rise at all.

Wikipedia sez: "Astronomical twilight is defined to begin in the morning, and to end in the evening when the center of the Sun is geometrically 18 degrees below the horizon." London, England is at 51 degrees north latitude. At midnight in the June Solstice, the Sun is at a declination of 23.5 degrees (approximately), so the over-the-pole angular distance is (90-51) + (90-23.5) degrees, or 105 degrees. The horizon is 90 degrees, so the Sun is 15 degrees below the northern horizon at midnight on June 21. So, no, it won't meet the definition for "darker than astronomical twilight".
At the June Solstice, the Sun is about 23.5 degrees north of the equator. London is at 51.5 degrees north latitude. So at midnight around the solstice, the Sun is (90-51.5) + (90-23.5) degrees north of London. So, the Sun is 105 degrees away from London. The northern horizon is 90 degrees, so the Sun is only 15 degrees below the northern horion.
The altitude of the sun is 72+ degrees, and actually closer to 73 degrees. (72 degrees 46+ minutes).
Viewed from latitude 55° north, the sun's highest altitude on June 21 is31.5° down from the zenith, or 58.5° up from the horizon.
It depends on where you live on the Earth. North of the equator the shortest day is on the Winter Solstice, about December 21st. In the Southern hemisphere the shortest day is on the Summer Solstice about the 21st of June.
On June 21st.
No. The southern border of Denmark is at 54 degrees 44 minutes north.Wikipedia sez: "Astronomical twilight is defined to begin in the morning, and to end in the evening when the center of the Sun is geometrically 18 degrees below the horizon."At midnight in the June Solstice, the Sun is at a declination of 23.5 degrees (approximately), so the over-the-pole angular distance is (90-54.5) + (90-23.5) degrees, or 102 degrees. The horizon is 90 degrees, so the Sun is 15 degrees below the northern horizon at midnight on June 21.So, no, it won't meet the definition for "darker than astronomical twilight".
