Here's a scholarly best-estimate of the chronological composition of the Hebrew Bible (Tanakh / Old Testament), based on linguistic analysis, historical context, and redaction criticism. This list reflects when texts were likely first composed, not when they reached final form. I've also noted books with multiple layers, later redactions, or composite authorship.

This timeline reflects scholarly consensus but is always evolving with archaeological and linguistic discoveries.
