Methodology
How Biblical Chronology Is Calculated
A transparent look at the moving parts behind every number on this page.
Summing the begetting ages in Genesis 11 under the Masoretic Text gives 292 years from the Flood to Abraham's birth. The Septuagint's larger patriarchal ages give roughly 942 years, the Samaritan Pentateuch about 292, and Ussher's reconciliation (Abraham born when Terah was 130) gives 352. Use the calculator above to see each figure and the step-by-step math.
Understanding the differences
Why Do Biblical Timelines Differ?
Biblical chronologies can legitimately arrive at different dates. The differences come from a small number of well-understood sources — none of them 'one system proven right.'
Different manuscript traditions
The Masoretic (Hebrew), Septuagint (Greek), and Samaritan Pentateuch record different ages in Genesis 5 and 11 — the largest single source of divergence.
Different genealogical numbers
Even within one tradition, begetting ages and total lifespans can differ (e.g. the LXX makes Jared, Methuselah, and Lamech live different lengths than the MT).
Interpretation of genealogical gaps
Some scholars read biblical genealogies as selective or telescoped, where 'father' may mean 'ancestor' rather than immediate parent.
Different dates for the Exodus
The 'early date' (~1446 BC, from 1 Kings 6:1) versus the 'late date' (~1260 BC, from Egyptian chronology) shifts everything after Moses.
The Judges period
Adding the Judges periods straight yields ~410 yrs, which may overlap or include concurrent oppressions; reconciling with 1 Kings 6:1 is debated.
Reconstructions of kings' reigns
The divided monarchy has overlapping reigns, co-regencies, and accession-year conventions that different chronologies resolve differently.
Co-regencies
Father-son co-regencies in Judah and Israel can compress or expand the timeline depending on whether reigns are counted as overlapping or sequential.
Ancient calendar systems
Accession-year vs non-accession-year reckoning, and different new-year conventions (Nisan vs Tishri), affect regnal totals.
Historical dating uncertainty
Anchoring biblical events to Egyptian, Assyrian, and Babylonian chronology involves its own uncertainties and cross-checks.

Sources & Methodology
Every number on this page is derived from a specific source. We distinguish biblical text from calculation, interpretation, and historical evidence — and we never invent citations.
Masoretic Text(MT)
The Hebrew text preserved by the Masoretes — the basis of most Protestant Old Testaments.
Method: Sums the patriarchal begetting ages in Genesis 5 & 11 as recorded in the Hebrew (MT).
Sources: Genesis 5; Genesis 11; 1 Kings 6:1. Creation anchored to 4004 BC for display.
Septuagint(LXX)
The Greek translation of the Hebrew scriptures (3rd–2nd c. BC). Genesis 5 & 11 record larger patriarchal ages than the MT.
Method: Uses the longer antediluvian & postdiluvian begetting ages of the LXX Genesis genealogies.
Sources: Genesis 5 (LXX); Genesis 11 (LXX). Display anchored to an estimated Creation of 5500 BC.
Samaritan Pentateuch(SP)
The Samaritan Hebrew text tradition. It shortens antediluvian lifespans but keeps begetting ages closer to MT in some places.
Method: Uses the distinctive SP ages in Genesis 5 (shortened lifespans; Flood in AM 1307).
Sources: Genesis 5 (SP); Genesis 11 (SP). Display anchored to an estimated Creation of 4054 BC.
Traditional Ussher Chronology(Ussher)
Bishop James Ussher's 17th-century chronology (Annals of the World), the most famous traditional dating.
Method: Uses MT numbers with Ussher's specific reconciliations (e.g. Terah 130 at Abraham's birth; 430-year sojourn from Abraham's call).
Sources: Ussher, Annals of the World (1658). Creation dated 4004 BC.
Biblical references cite the verse that states the number used (e.g. "Genesis 5:5" for Adam's 930 years). Manuscript-tradition differences come from the MT, LXX, and SP texts of Genesis 5 and 11. Historical dates for the monarchy and later periods draw on standard scholarly chronology (1 Kings 6:1; Assyrian and Babylonian synchronisms). Where a date is uncertain we display a range and label its confidence level. We do not fabricate scholarly citations; only sources represented in our data are shown.
