These dates reflect traditional conservative evangelical estimates, tying composition closely to the lifetimes of attributed authors and historical events (such as an early Exodus around 1446 BC). Exact years are impossible to determine, but these represent the narrowest ranges and closest approximations to specific years upheld in traditional conservative Christian scholarship (e.g., sources like the Expositor's Bible Commentary, Edwin Thiele's chronology, and early-dating advocates). While broader scholarly consensus varies, and some books (like Psalms) span multiple authors and periods, these are the most precise timelines available within longstanding conservative Christian teaching.
