The oldest form of astrology was used by the common people for the purpose of growing their food. Animal calendars, an imaginative invention of looking at the Moon passing over/through/near groupings of stars and correlating their movements to the seasonal cycles of various animals as they mated, migrated, etc., were drawn up to help track the best times for sowing seeds, cultivating and growing plants, dealing with pests, harvesting, and collecting seeds.
