During an equinox, the length of night and day across the world is nearly, but not entirely, equal. This is because the day is slightly longer in places that are further away from the equator, and because the sun takes longer to rise and set in these locations. Furthermore, the sun also does not set straight down, but it also moves in a horizontal direction.
During the March equinox, the length of daylight is about 12 hours and eight to nine minutes in areas that are about 30 degrees north or south of the equator, while areas that are 60 degrees north or south of the equator observe daylight for about 12 hours and 16 minutes. Many regions around the equator have a daylight length about 12 hours and six-and-a-half minutes during the March equinox.
Moreover, one day does not last for the exact same 24 hours across the world and due to time zone differences, there could be a small difference in the daylight length between a far-eastern and far-western location on the same latitude, as the sun moves further north during 24 hours.
