Equal Light “Equilux” is drawn from the Latin terms for equal (equi) and light (lux). So how do we find out which dates fit the description and qualify as truly equal day and night? To measure the day/night split in a 24-hour span, astronomers use common definitions of sunrise and sunset.

Sep 22, 2023 · There are days when, after accounting for these factors, day and night are indeed equal in length. One of these days occurs a few days before the March equinox, and the other is a few days after ...
Jan 18, 2024 · You can see how the curve oscillates around the point (0 °, 12 h) (0\degree,12\ \mathrm{h}) (0°, 12 h): at the equator, every day has the same length! Let's fix a point on the horizontal axis. We can see how the daylight hours vary for a specific location: the following image represents the daylight hours across an entire year for the ...
Mar 20, 2021 · The duration of day and night are almost never equal on Earth because our planet’s axis is tilted. That’s why equinoxes (and solstices, see notes 1) occur. That’s also why we have seasons. So, the Sun’s center is usually not on the equator for most of the year. When the center of the Sun’s disc crosses the equator, astronomers define ...
In other words, night and day are, in principle, the same length all over the world. This is the reason it’s called an “equinox,” derived from Latin, meaning “equal night.” However, this is literal translation not entirely true. In reality, equinox days don’t have exactly 12 hours of daylight and 12 hours of dark.
