Where Did Our Calendar Come from? People have not always had a strong interest in the past or the future. Long ago, they did not need to keep an exact record of the changing seasons. But when men and women began to settle and depend heavily on farming, they needed to form a calendar. If crops were not sown and harvested at the right time of year, there would not be enough food for people to eat. This was especially important in ancient Egypt where life revolved around the annual flooding of the river Nile. Egyptians noticed that the Nile floods came at about the same time each year. They always started around the day when the bright star Sirius appeared on the horizon just before sunrise. As a result, this day was taken to mark the start of the Egyptian year. The year was then split up into 12 months of 30 days. Five extra days were added at the end to make 365 in all. Using this scheme, the Egyptian calendar kept reasonably in step with the seasons.
