Bonus Knowledge

Did you know that the concept of minutes and hours dates back to ancient civilizations? The Sumerians, around 3000 BC, divided the day into 12 hours, and the Egyptians adopted a 24-hour day by using sundials. Each hour was further divided into 60 minutes, and this sexagesimal system (base-60) still influences our timekeeping today!
In practical terms, knowing that 15 minutes is a quarter of an hour can be incredibly useful for time management. Use this knowledge to break your tasks into segments! For example, if you’re studying, try studying for 15 minutes followed by a 5-minute break. This technique could help maintain your focus and energy throughout the session!
