Subject: Static GK (General Knowledge)

Book: General Time Knowledge

Ancient Egyptians and Babylonians influenced the 24-hour day we use today, originally tying measurements to the base-12 or base-60 number systems. Daytime was once divided into 12 segments, and nighttime into another 12. This led to the 24-hour structure that has persisted for millennia. Attempts to decimalize hours have appeared throughout history but never gained significant traction. Understanding the 24-hour day’s origins clarifies how deeply historical roots shape modern conventions, even in an era that increasingly values standardization and simplicity.
