What made the Egyptian lunar calendar difficult to use?

Answer 1

The Egyptian lunar calendar was difficult to use because it was based on the cycles of the moon, which is approximately 29.5 days long. However, the exact duration of the lunar cycle is slightly different from month to month. This made it challenging to accurately predict and determine the start and end of each month, leading to inconsistencies and inaccuracies in aligning the calendar with the solar year. Additionally, the Egyptian calendar did not have a leap year system, which over time caused it to drift out of sync with the actual seasons.
