The tilt of the Earth's axis relative to our orbit around the Sun causes the seasons. Here in the northern hemisphere, the amount of sunlight peaks on June 20 or 21, at the summer solstice, and the amount of sunlight decreases every day after that until December 20 or 21, the winter solstice. (The date varies with the cycle of the leap years.)
Today is December 19, and the Winter Solstice this year occurs on December 21, 2008 at 4:04 AM PST which is 12:04 UT (Universal Time). So Sunday the 21st will be the shortest day of the year, and starting on December 22, the amount of sunlight will increase by a minute or two per day until the Summer Solstice on June 21.

What date do we gain daylight?
We gain daylight after the winter solstice, which usually occurs around December 21st in the Northern Hemisphere. From that point on, the days gradually become longer until the summer solstice in June.
What month do you start to lose daylight?
You start to lose daylight in the northern hemisphere around late June. This is when the summer solstice occurs, marking the longest day of the year. After this point, the days start getting shorter until the winter solstice in late December.
Are the days longer or shorter in the northern hemisphere right after the autumnal equinox?
In the northern hemisphere, the days become shorter right after the autumnal equinox. This is because the amount of daylight decreases as the hemisphere tilts away from the sun, leading to shorter days and longer nights.
How many hours of daylight for Dec 22 2011?
Well it depends on what day it is but today is November 20. so 10 days until December. . plus 31 is 41. Then 365 days until 2012 is 406. THEN add 365 again minus 10 . SO. . . 406 days plus 355 is 761. 761 days till December 21, 2010 . counting from November 20, 2010.
Does it get dark on January at 5?
That depends on the country & time zone you are in At the South Pole it will stay daylight for most of the day, but during November & December it is almost 24 hour sunlight If you're at the North Pole, there will be very little sunlight In the northern hemisphere it gets dark in early afternoon, while in the southern hemisphere it is summer, so it's light until well into the evening
What happens to the daylight period in the northern hemisphere after June 21?
After June 21, which is the summer solstice, the daylight period in the northern hemisphere starts to decrease gradually. This marks the beginning of summer transitioning into fall, with days becoming shorter until the winter solstice in December.
What date do we gain daylight?
We gain daylight after the winter solstice, which usually occurs around December 21st in the Northern Hemisphere. From that point on, the days gradually become longer until the summer solstice in June.

Are the days longer or shorter in the northern hemisphere right after the autumnal equinox?
In the northern hemisphere, the days become shorter right after the autumnal equinox. This is because the amount of daylight decreases as the hemisphere tilts away from the sun, leading to shorter days and longer nights.
What month was summer 1942?

How is it spring in Antarctic in November?
The seasons differ by six months between the northern and southern hemispheres. The spring season is from about March 21st until June 21st in the northern hemisphere and from September 21st until December 21st in the southern hemisphere.
How many minutes a week does the daylight get longer?
It is not a linear process but a sinusoidal process. The daylight period increases most rapidly at the Spring equinox. The rate of increase slows to 0 at the Summer solstice, after which it starts decreasing. The rate of decrease reaches a maximum at the Autumn equinox after which it starts easing up. It reaches 0 at the Winter solstice after which it starts increasing until the Spring. Remember, though that Spring in the Northern hemisphere is offset by six months compared to the Southern hemisphere, and so on. Thus, when daylight hours are increasing in the Northern hemisphere, they are decreasing in the Southern hemisphere. The periodicity of this process is a year. The rate of maximum increase (or decrease) per week depends on the latitude. In the polar regions, the day length reaches 24 hours during the Summer and cannot increase further. Similarly, during the Winter, daylight length decreases to 0 and cannot decrease further.
How many minutes daylight gained?
The amount of daylight gained varies depending on your location and the time of year. Generally, around the time of the spring equinox, many places in the Northern Hemisphere can gain approximately 2 to 3 minutes of daylight each day as the days lengthen. This increase continues until the summer solstice, after which daylight begins to decrease again. For specific details, it's best to check local sunrise and sunset times.
Why does the length of daylight increase from March 1st to March 31?
The reason that the time between sunrise and sunset gradually increases from late December until late June in the northern hemisphere is that the portion of the northern hemisphere that is illuminated by the sun gradually increases during that time from a minimum of about 37% to a maximum of about 63% due to the relationship between the direction of the tilt of the Earth's rotational axis and the direction of the sun.
When do daylight hours start getting longer?
In the northern hemisphere, daylight hours start getting longer after the Winter Solstice, December 21. The daylight continues to legthen everydy until Summer Solstice, June 21. Then the reverse happens. The daylight gradually reduces until Winter Solstice arrives again.
