Twice a year, at the equinoxes. These are generally on March 21, and September 21. These dates can vary a day either way, depending on the cycle of leap years.
At some point there is a balance between the daylight hours and nighttime hours but I do not know the exact date or time period.
The first day of the year with exactly 12 hours of daylight varies depending on your location. In general, this occurs around the spring or autumn equinox when the sun is directly above the equator, leading to equal day and night lengths.
The duration of Date Night is 1.47 hours.
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.

They're the same length on either side of the date of the equinox, which falls in March and September. In 2009 those dates were 3/20 and 9/22, respectively. Just count days on either side of those dates, to answer our question. What ends up happening, is that the first 20 days of March will have roughly the same length of daylight as the 20 days AFTER the September equinox (i.e. 9/22 thru 10/11). Similarly, the first twenty days of September will have the quality of daylight shown for the first 20 days after the spring equinox (3/20 thru 4/9)
That depends on your location and the date. On average, you get 12 hours of daylight; more in the summer, but less in the winter.
That would depend on where you live, and which part of autumn you mean. The definition of "autumn" is the period between the autumnal equinox and the winter solstice, so the number of hours of daylight would be "less than 12, and decreasing". On September 22, the number of hours of hours of daylight would be only a minute or so less than 12 hours, while on December 19 the length of the day will be somewhere between 11.9 hours and zero, depending on your latitude.
The number of days of daylight depend not only on the date, but also on your geogrpahical lotation, specifically your latitude.

No matter where you are, the Summer Solstice is the longest day of the year (well, the most hours of sunlight).Otherwise, technically, when you set the clocks back an hour in the fall, that particular day has 25 hours instead of 24.
Changing the time zone or daylight saving time settings on a device can affect both the date and hours displayed. Additionally, manually adjusting the date and time settings on a device can also impact both the date and hours shown.
