The Venus tablet of Ammisaduqa is the record of astronomical positions for Venus, as preserved in numerous cuneiform tablets dating from the first millennium BC. It is believed that this astronomical record was first compiled during the reign of King Ammisaduqa, the fourth ruler after Hammurabi. Thus, the origins of this text could probably be dated to around the mid-seventeenth century BC despite allowing two possible dates.

The chronology of the ancient Near East is a framework of dates for various events, rulers and dynasties. Historical inscriptions and texts customarily record events in terms of a succession of officials or rulers: "in the year X of king Y". Comparing many records pieces together a relative chronology relating dates in cities over a wide area.
