In which dynasty did our ancestors invent the method of observing astrological phenology?

I think this should be very early, because things like calendars appeared very early. The earliest time should be the legendary calendar in the Xia Dynasty, because I think this time should be very early, and it may have appeared before the country came into being. After all, this is closely related to agricultural civilization, and it is precisely because of this method that agricultural civilization can develop better.
