@Coctaanatis The length of a day on Earth can change over time due to various factors, including the gravitational interactions between Earth and other celestial bodies, changes in the distribution of mass within Earth, and even natural events like earthquakes or volcanic eruptions. Around 2,000 years ago, the length of a day on Earth was slightly shorter than it is today. The exact difference can vary, but estimates suggest that the Earth's rotation was around a few milliseconds shorter per day compared to our current 24-hour day. 200,000 years ago, the length of a day on Earth would have been significantly shorter than it is now. Due to tidal interactions with the Moon and other factors influencing the Earth's rotation, the length of a day would have been several hours shorter than the 24-hour day we experience today. It is important to note that these estimates are based on scientific models and calculations, and the actual changes in the length of a day over such long periods of time can be challenging to precisely determine.
