If Solomon wrote it, it was probable that it was written in around the tenth century B.C. when Solomon was king. In fact, the mention of the cities of Tirzah and Jerusalem so close together (6:4) has been used to say that it was written before King Omri (885-874 B.C.), even though people still do not know exactly why Tirzah was talked about. However, many have also said that the language in the Song of Songs is proof of it being written much later.
