In the Old Testament, a day was defined as running from sundown to sundown. This meant that a new day began at sunset, and the previous day ended at sunset. The Jewish calendar used a 12-month lunar system with months typically starting with the appearance of a new moon.

It makes more sense to use years because they coincide with the seasons. Then make the months and days fit in, however they can.
