Background: Daniel's Timelines: 70 Weeks and 3½ Years

A Note for Group Leaders Before You Start

This is the densest session in the introduction, covering two distinct but related time schemes (Daniel’s 70 “weeks” and Revelation’s parallel 3.5-year expressions). If your group tends to meet weekly without the constraint of a single Sunday service, consider splitting this into two sessions — Part 1 on the 70 weeks, Part 2 on the 3.5 years — rather than rushing through both in one sitting. What follows is written as one complete session, but the natural break point is marked clearly below.

Opening Hook

Ask your group: has anyone tried to build a timeline chart of end-times events from Daniel and Revelation’s numbers — 70 weeks, 1260 days, 42 months, “time, times, and half a time”? These numbers have fueled more speculative date-setting than almost anything else in Scripture. Tonight we’re going to do the math carefully, see where it points with real precision (startlingly, to the cross itself), and be honest about where the source material’s own chronology needs a correction before we build anything on it.

Part 1: The 70 Weeks

The full argument is in expl/bible/daniel/the-70-year-weeks.md.

What a “week” means here. God commanded a Sabbatical year every seventh year (Leviticus 25:1-7), which Israel never actually kept. When exile came, it lasted 70 years — one year for every missed Sabbatical year (2 Chronicles 36:20-21), which means 70 missed Sabbaticals span 7×70=490 years, roughly the whole span of Israel’s national existence to that point. That’s why a “week” in Daniel means seven years, not seven days — deliberately echoing the Sabbath pattern.

The prayer and its answer. Daniel, aware of Jeremiah’s 70-year promise (Jeremiah 29:10), prays for his people (Daniel 9:3-19) and receives an answer covering “seventy sevens” — 490 years — decreed to finish transgression, end sin, atone for wickedness, bring in everlasting righteousness, seal up vision and prophecy, and anoint the Most Holy Place (Daniel 9:24-27). Taken together, these six goals go well beyond anything achieved in history except what Jesus accomplished on the cross.

A significant correction to the source material’s chronology. The article’s original sequence claims 7 weeks (49 years) run from the decree to rebuild Jerusalem to 539 BC, and then 62 weeks (434 years) run “while the temple stands” — but it anchors that second period starting from 440 BC (attributing the temple’s rebuilding to Nehemiah) and ending at 6 BC. Two things need fixing here. First, the Second Temple was actually completed in 516 BC under Zerubbabel and Darius I — Nehemiah’s contribution, decades later (c. 445 BC), was rebuilding Jerusalem’s walls, not the temple. Second, and more importantly, the numbers as originally presented don’t actually chain together: starting the 49-year count at 587 BC and ending it at 539 BC, then separately starting the 434-year count at 440 BC, leaves an unexplained gap of roughly 99 years that Daniel 9:25 describes as running back-to-back, not with a century-long pause in between. This is a real argumentative weakness in the source material, not just a rounding error — treat the overall “seventy sevens converge on the cross” conclusion as a well-supported historical pattern worth taking seriously, while being honest with your group that the precise decade-by-decade math depends on which of several proposed starting points (Cyrus’s decree, Darius’s decree, or Artaxerxes’ decree to Ezra/Nehemiah in 457 or 445 BC) you choose — a genuinely contested detail among careful readers of Daniel, not a settled one.

The last “week,” and the cross. After the sixty-two sevens, “the Anointed One will be put to death and will have nothing” — Jesus, not Cyrus this time. “Cut off” in Aramaic can also mean “cut a covenant” — He died in order to make one. In the middle of the final seven-year period, sacrifice and offering end, because they’re no longer needed after the cross (Hebrews 10:1-18). The source material even proposes a specific 7-year window — AD 27 (Jesus’s baptism) to AD 34 (Stephen’s martyrdom and the gospel’s decisive turn toward the Gentiles) — with the cross itself at the midpoint, AD 31. Hold this specific dating with appropriate openness: it’s a plausible, carefully reasoned proposal, not a certainty the whole argument depends on.

Part 2: The 3.5 Years

The full argument is in expl/bible/daniel/the-secret-of-the-3-5-years.md.

The math. Revelation’s chapters 11-13 use three different expressions for what turns out to be the same length of time, assuming a 30-day month: 1260 days = 42 months = “time, two times, and half a time” = 3.5 years. Five separate references (Rev 11:2, 11:3, 12:6, 12:14, 13:5) all point to this same underlying period.

Original-language and background note: Elijah’s drought. Elijah announces a drought against Jezebel’s Baal worship that lasts, per Jesus’s own reference to it, 3.5 years — even though 1 Kings itself never states the exact duration. The whole episode turns on one question: who is the true God, the one who sends rain and fire from heaven? Notably, the second beast in Revelation 13 performs that exact same feat — calling down fire — a deliberate, unsettling echo of Elijah’s Mount Carmel test, this time performed by a counterfeit.

How the 3.5-year pattern already surfaced in Daniel. The 70 weeks resolve, in their final period, into two half-weeks of 3.5 years each — one commonly read as covering Jesus’s earthly ministry, the other extending into the age of the church that follows. This is the same period, described three different ways for reasons the source material treats candidly as somewhat uncertain (more below).

What the three time periods likely describe. Chapter 13’s beast activity begins right after the cross, once the devil realizes he cannot destroy Israel directly, and runs until Christ’s return. The woman (representing God’s people) is protected in the wilderness for the same span. The temple’s outer court, no longer used for sacrifice, is trampled by the nations for the same period — again running from the cross to the second coming. That leaves the two witnesses' 1260 days, which likewise span the whole age between Christ’s two comings — a real clue, given how long that is, that “the witnesses” function much more plausibly as the church itself than as two individual end-times figures (we’ll pick this up fully in the Two Witnesses session much later in the series).

An honest, flagged uncertainty — good material for discussion, not a settled answer. Why does the text switch units (days here, months there, “times” elsewhere) for what’s mathematically the same length of time? The source material proposes that days mark the church’s witness, months mark the devil’s apparent reign, and years/times mark God’s hidden work — but the material’s own author flags this as “admittedly speculative,” and it doesn’t cleanly resolve one real tension: the same event (the woman’s protection) is described using both “days” (Rev 12:6) and “times” (Rev 12:14), which sits awkwardly with a clean three-way symbolic scheme. This is a good place to let your group wrestle with the text directly rather than handing them a tidy answer the material itself doesn’t fully deliver.

Discussion Questions

Understanding the text:

1. Why does the “seventy sevens” prophecy point so precisely toward the cross, even though the exact decade-by-decade math is more contested than a quick read might suggest?
2. What does the switch between “days,” “months,” and “times” for the same underlying length of time suggest is happening in Revelation 11-13 — and why is it more honest to name the unresolved tension here than to force a tidy explanation?
3. How does the Elijah/Mount Carmel background illuminate what’s happening when the second beast in Revelation 13 calls down fire from heaven?

So what for us: 4. Daniel’s precise, sober arithmetic converges on the cross rather than a random future date. How does that reshape your instinct to look for coded predictions of near-future events in these same numbers? 5. The “1260 days” almost certainly describes the whole church age, not a short future tribulation period. If the church has already been living out its “1260 days” of witness for two thousand years, what does that suggest about your own role in that ongoing story right now? 6. This session modeled holding a conclusion firmly (the cross is the target) while holding some details loosely (the exact chronology, the days/months/times pattern). Where else in your own faith could you benefit from that same combination of confidence and humility?

Closing Prayer Prompt

Thank God for the staggering precision of a prophecy written centuries in advance that converges on the cross itself. Ask for the wisdom to hold Scripture’s genuinely mysterious details with humility, without needing to force every number into a tidy chart before you can trust the God who gave it.
