Are the hours of daylight and darkness in September equal to March hours of daylight and darkness?
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)
How long are the days and nights in January and in July?
In terms of daylight and darkness, that will depend on where in the world you are. If you are in the Antarctic, then it is bright all of the time, with no darkness, in January and completely dark with almost no light in July. It would be the reverse in the Arctic. If you were on the equator, it would be about 12 hours of light and 12 hours of darkness all year. Between the equator and the poles, the amount of darkness and daylight will vary, getting more extreme the closer to the poles you get.
