No day lasts 6 months in the northern hemisphere. A day is 24 hours, with the exception of days where the hour changes, in which case you have a 23 hour day when the clocks go forward and a 25 hour day when the clocks go back. What you are probably referring to is the length of daylight. Around the Arctic, the Sun does not set for very long periods of time. At the North Pole it can be up for 6 months and down for 6 months. So the answer you are looking for is the North Pole.
There is no time between these. On the day before the autumnal equinox, the sun is directly overhead in the northern hemisphere (at a latitude just north of the equator). The following day, it is directly overhead in the southern hemisphere (just south of the equator). The sun goes from being overhead in the northern hemisphere to the southern hemisphere instantaneously, the change happening at the autumnal equinox.
December 21st or 22nd is the shortest day of the Northern Hemisphere--known as the Winter Solstice.
24 Hours
In the northern hemisphere it will the 21st of June. In the southern hemisphere, it is on the 21st of December 2018.
The shortest day of the year in the southern hemisphere is the same day the the northern hemisphere has it's longest day, the Summer Solstice. Which occurs on either June 21 or 22.
You're reading a calendar using your northern-hemisphere centric orientation. Antarctica is in the southern hemisphere, with reversed seasons from those experienced in the northern hemisphere.
Shortest day, December 21 st. This only applies in the northern hemisphere. The answer will vary by six months in the southern hemisphere!

The autumnal equinox is not in December. In the northern hemisphere it is in September. In the southern hemisphere it is in March. In December you have the winter solstice in the northern hemisphere and the southern hemisphere has the summer solstice. Equinoxes and Solstices happen on the 21st of their respective months, though occasionally then can be on the 20th or 22nd.
It is the winter solstice in the northern hemisphere, when the northern hemisphere is tipped furthest from the sun, resulting in the shortest amount of daylight in the year in the northern hemisphere. In the southern hemisphere, it would be the day with the longest amount of daylight.
For the northern hemisphere, Autumn normally begins on September 22, but sometimes it can begin on September 23. The last day of Autumn is December 20, so the Autumn months are really October, November, and December. For the southern hemisphere, the first day of Autumn is March 20. The last day of it is June 20. The Autumn months for the southern hemisphere are April, May, and June.
The shortest day in the Northern Hemisphere is December 21st.
If May 15 gains time each day, it means the days are longer than 24 hours. If May 15 loses time each day, it means the days are shorter than 24 hours. However, in reality, the length of a day remains constant at 24 hours due to Earth's consistent rotation.
when the Northern hemisphere is tilted more toward the Sun.
the same day that begins the spring in the northern hemisphere
December 21st or 22nd is the shortest day of the Northern Hemisphere--known as the Winter Solstice.
The longest day of the year, also known as the summer solstice, occurs around June 21st in the Northern Hemisphere. It is when the North Pole is tilted closest to the sun, resulting in the longest period of daylight for that hemisphere.
