Review Questions

• How did the implementation of the 365-day calendar influence agricultural practices in ancient civilizations?
  • The implementation of the 365-day calendar was crucial for ancient civilizations as it aligned agricultural practices with seasonal changes. By accurately tracking time, societies could predict weather patterns and determine optimal planting and harvesting periods. This synchronization led to improved crop yields and food security, enabling civilizations to flourish and develop more complex societal structures.
• Discuss the differences between the Julian and Gregorian calendars in terms of how they addressed the inaccuracies of timekeeping.
  • The Julian Calendar established a system of a 365-day year with a leap year every four years, which created an annual average of 365.25 days. However, this method was still slightly inaccurate due to the actual solar year being about 365.2422 days. The Gregorian Calendar adjusted this by introducing a more complex leap year rule that omitted certain leap years in centurial years unless divisible by 400, thus refining accuracy in aligning the calendar with solar cycles.
