Aviv an unclear term

As much as I want things to be clear, there are still many things we do not know about ancient agriculture. In this video, I explain the dilemmas around the concept of Aviv. Aviv is used to determine the beginning of the harvest cycle and the biblical feasts. However, we do not have enough information to determine the exact stage the grain needs to be in which causes issues. I hope this video will encourage more discussion so we can have a clearer understanding of things.
