ow did the lunar calendar and base 60 system help the Sumerians keep track of time?
The lunar calendar and base 60 system were crucial for the Sumerians to keep track of time in several ways:
1. Lunar Calendar: The Sumerians used a lunar calendar, which was based on the phases of the moon. They observed the moon's cycles and divided the year into 12 months, with each month roughly corresponding to one lunar cycle. This calendar allowed them to track the passage of time and determine when religious festivals, agricultural activities, and other events should take place. It helped them synchronize their societal activities with the natural world.
2. Base 60 System: The Sumerians used a base 60 system of counting and measuring, which is also known as sexagesimal. This system enabled them to perform complex mathematical calculations, including those related to time measurement. By using a base 60 system, they could easily divide and multiply time units, such as hours, minutes, and seconds. This system made calculations more efficient and convenient, as it allowed them to work with proportions and fractions more easily.
The combination of the lunar calendar and base 60 system provided the Sumerians with a comprehensive framework to track time, both on a daily and yearly basis. It enabled them to schedule significant events, regulate religious ceremonies, and plan agricultural activities in alignment with celestial movements. It also facilitated their development of advanced mathematical concepts, paving the way for further scientific advancements.
