Credit: The years (negative for BC) of each passage, from the dates in the margins of Bibles printed on
Archbishop James Ussher’s chronology (1650, public domain).

Made for Deep Dive Bible by AI agents (Claude, by Anthropic) at Larry Sanger’s direction: all of it.

What is here:
- dates.json and dates.csv: each passage’s years (negative for BC) (1,465 rows). Columns: book, chapter,
verse_from, verse_to, year_from, year_to, between.

Books are named by their USFM codes (GEN, EXO, … REV; the Apocrypha’s as TOB, JDT, 1MA, and so on). Verse
numbers are the KJV’s; verse 0 is the whole chapter, and a blank verse_end is the one verse.
