Continuous Jubilee Calendar (CJC): Bible Chronology, Daniel's 70 Weeks, and the Crucifixion Date

The Continuous Jubilee Calendar (CJC) is a free, open research project that counts the Bible's 49-year Jubilee cycles (Leviticus 25) without a break, from the Exodus to today, using one simple formula, and then tests the results against history, astronomy, and ancient records. Anyone can check every step by hand.

What the calendar shows

• Daniel's seventy weeks run from Jubilee to Jubilee. The decree of 457 BC falls in a Jubilee year, and 490 years later, so does AD 34: exactly ten Jubilee cycles.
• 483 years after the decree (Daniel 9:25), the count reaches AD 27, the start of Jesus' ministry.
• The crucifixion, Friday, April 7, AD 30, falls in "the midst of the week" (Daniel 9:27): the exact middle of the final seven years. AD 33 lands at the end instead.
• Hezekiah's deliverance from Assyria (702 BC) also falls in a Jubilee year.
• The seven-year sabbatical rhythm matches independent records: the Maccabees, Josephus, ancient gravestones from Zoar, and the Jewish shemitah year still kept today.
• Every result is labeled honestly: what is arithmetic, what is historical evidence, and what is interpretation. The misses are shown too.

A companion kit, The Great Tribulation, The Second Coming, and The Rapture, answers end-times questions from Scripture (KJV) and the papers only, with no web searching, including 28 common objections answered from Scripture. Its homepage card (for Claude, ChatGPT, or Gemini) has two buttons: Ask: Quick Answers and Ask: Full Studies. The kit is at https://scripturescjc.com/tribulation-kit.txt and is built automatically from kit-source/tribulation/ in the Continuous-Jubilee-Calendar repo.

The formula in one line

For any year: B = year + 1437 (AD) or 1438 − year (BC); Cycle = (B − 1) ÷ 49, rounded down, + 1; Y = B − (Cycle − 1) × 49. Year 1 is a Jubilee; Y ÷ 7 with no remainder is a sabbatical year.
