Depending on where you are on the continent, you can experience 24 hours of sunlight each day during the summer months.
Whatever answer I give you will be wrong in 12 hours. The Earth spins on its axis every 24 hours, so each side of the planet gets about 12 hours of day light per day. (Less in winter, and more in summer, due to the 23 degreetilt of the axis.)
Actually, summer lasts for three months in Antarctica and begins on December 21 each year.
The equator gets 12 hours of daylight and 12 hours of darkness each day throughout the year.
Spain has 14 hours of sun light
Twenty-four hours of daylight.
Only at the Equator is this true. Light and darkness, or day and night, are less evenly divided the further away from the Equator you go, depending on the season. At the Poles it's either dark(winter) or light (summer) for virtually the entire 24 hour period each day. About half way between the Equator and the Poles, like much of Europe, you have 15 to 16 hours of daylight in summer and equally long nights in winter.
summer It could be roughly a trade-off between spring and summer. Spring culminates at the summer solstice, and that is when summer begins. Each trails off from the summer solstice, in different directions of time, ending with the equinoxes. The three month period with the most hours of sunshine would be mid-spring through mid-summer.
The answer is given after the list of "these" days.
Each light and each color is individually set. You would need to contact the street department for that area to get the specific information.
to feminize it you must give it 12 hours of light and 12 hours of darkness each day.
Fish need both light and dark cycles just like people do. The light should be on for 12 hours and off for 12 hours each day. The easiest way to do this is to place the aquarium light on a timer.
