Overall, the Earth is a good timekeeper: the length of a day is consistently within a few milliseconds of 86,400 seconds, which is equivalent to 24 hours. However, over the course of months and years, these small differences can add up and put our clocks out of sync with the Earth's spin.

24 maj 2024 · Day length is determined by the length of time the Sun is above the horizon. Day length changes through the year as the orientation of the Earth to the Sun changes. The circle of illumination is the imaginary circle that separate day from night.
7 sie 2023 · Over months and years, the length of each day varies by tiny increments of time in agreement with Earth’s shifting systems. These shifts do not significantly affect the total hours of daylight or nighttime in a given season, but instead refer to millisecond shifts in the measurement of a 24-hour day.
