# The Book of Days

Bitcoin's year, kept by Hal

# The Book of Days

The Book of Days gives Bitcoin a year to keep. The civil calendar sets the fixed feasts. The chain sets the moveable ones, and our own node, Hal, keeps that clock: every date below that depends on a block comes from blocks Hal has verified for itself.

Hal is catching up. These are his last good numbers.

## White Paper Night

Sat, Oct 31, 2026

In 7 days

**It remembers:** The white paper reached the mailing list, October 31, 2008.

**The rite:** Read the nine pages aloud. Candy for the children, a pamphlet for the adults walking with them.

Before then, the next Turning: block 973,728, 893 blocks from Hal's tip. Hal's estimate: Thu, Oct 29, 2026, 12:48 PM ET, give or take about 16 hours; at exactly ten minutes a block, Thu, Oct 29, 2026, 10:41 PM ET.

## The fixed feasts

The Bitcoin year begins on White Paper Night, October 31, the way the church year begins in Advent. Each date below shows the feast's next turn on the calendar.

| Date | Observance | What it remembers | The rite |
| --- | --- | --- | --- |
| Sat, Oct 31, 2026 | White Paper NightHal now: Day 6,567 since the white paper. | The white paper reached the mailing list, October 31, 2008 | Read the nine pages aloud. Candy for the children, a pamphlet for the adults walking with them |

| Wed, Feb 24, 2027 | Gox RemembranceHal now: Hal's audit of Oct 23, 2026 counted 20,102,382.37 BTC in 164,557,923 unspent outputs. | Mt. Gox went dark, February 24, 2014 | Restore your wallet from its words and reread your letter to your family |

The stretch from Genesis Day to First Send forms a season of its own, the Nine Days of Genesis: the nine days the network took to go from its first block to its first payment between two people. Nine pages open the year, and nine days begin it.

## The chain's feasts

The chain keeps its own time, about one block every ten minutes. These feasts fall on a block height, not a date, so every date here counts as an estimate from Hal's average block time.

| Feast | Block | Blocks left | Feast day | Hal's estimate | At 10 minutes | How close |
| --- | --- | --- | --- | --- | --- | --- |
| The TurningHal now: 1,206 of 2,016 blocks (59.8%). Est. Oct 29, 2026, ± 15 h. Difficulty +5.0% at this pace. | 973,728 | 893 | Thu, Oct 29, 2026 est. | Thu, Oct 29, 2026, 12:48 PM ET | Thu, Oct 29, 2026, 10:41 PM ET | give or take about 16 hours |
| The Millionth BlockHal now: 27,082 blocks left. | 1,000,000 | 27,165 | Sat, Apr 17, 2027 est. | Sat, Apr 17, 2027, 9:01 PM ET | Fri, Apr 30, 2027, 9:21 AM ET | give or take about 11 days |
| The Halving JubileeHal now: 77,082 blocks left. Subsidy 3.125 BTC now, 1.5625 BTC after. | 1,050,000 | 77,165 | Tue, Mar 7, 2028 est. | Tue, Mar 7, 2028, 12:35 AM ET | Tue, Apr 11, 2028, 2:41 PM ET | give or take about 29 days |
| The MeridianHal now: 182,082 blocks left. The epoch stands 63.3% done. | 1,155,000 | 182,165 | Wed, Jan 16, 2030 est. | Wed, Jan 16, 2030, 7:44 PM ET | Wed, Apr 10, 2030, 6:41 PM ET | give or take about 2 months |

Hal stood at block 972,835 at Fri, Oct 23, 2026, 5:51 PM ET. Each estimate takes the blocks left and multiplies them by Hal's average block time over its last 2,016 blocks, from block 970,819: 9 minutes 20 seconds. Beside it, the same count at the protocol's target of exactly ten minutes a block. Blocks arrive at random and the network's hashing power drifts, so each date carries a margin: two standard deviations of block luck plus a 5 percent swing in the pace. A date a few days out lands within hours; a date years out can move by months. Hal refreshes these every evening. [How Hal sets these dates](https://bitcoinhashpoint.com/hal/).

| Feast | When | What it remembers | The rite |
| --- | --- | --- | --- |
| The Turning | Every 2,016 blocks | The network's difficulty reset | Stack your regular amount and check your keys |
| The Millionth Block | Block 1,000,000 | A million blocks with no rewrite of history | Watch it arrive together and write down where you were |
| The Halving Jubilee | Every 210,000 blocks | The issuance schedule keeping its word | A vigil for the block, after the Long Wait: forty days of skipping one purchase and saving the difference |
| The Meridian | 105,000 blocks after each Jubilee | The middle of each four-year epoch, 105,000 blocks after a Jubilee | The Meridian Letter: write yourself what you hold, why you hold it and what you hope for. Seal it and open it at the next Jubilee |

## The record

Hal read these from its own copy of the chain's headers. Times show when each block's miner stamped it, in Eastern time.

## The rites

Four rites mark a Bitcoiner's life outside the calendar, and a fifth makes the rest real.

First KeysA newcomer writes down recovery words for the first time, restores the wallet from them and receives a first gift of sats from a sponsor who walked them through it. Every Bitcoiner owes someone a First Keys.

The PamphletOne sheet of paper, handed to a person who asks: what bitcoin is, why it holds value, how to take custody and where to read the white paper. Hashpoint will publish a printable version before each White Paper Night. [Get this year's pamphlet](https://bitcoinhashpoint.com/white-paper-night/).

The Abundance CountAt the Feast of Abundance, each person at the table names one thing that costs less work today than it did for their grandparents: light, a phone call, a shirt, a library in a pocket. Then the table counts how much of that gain the dollar hid.

The Handing DownAt a marriage, a birth or a fiftieth birthday, a holder writes or updates the letter of instruction from Chapter 8 and walks an heir through a restore.

**The Naming.** A node that has synced from the first block and checks every rule for itself is the rite that makes the rest real. When a new node reaches the tip for the first time, its keeper gives it a name and writes down its birth block. From that day on, no one has to take anyone's word about their money.

The Hashpoint's node is named Hal, after Hal Finney, who ran the first node besides Satoshi's. Hal was born at block 970,981 on Mon, Oct 12, 2026.

## The rule of the pamphlet

The old door-to-door campaigns promised a reward after death that no one could confirm. This one offers freedom anyone can check tonight. That difference sets the rules.

1. **They knock. You answer.** Halloween is the one night the neighbors come to your door. Offer, never chase.

2. **Candy for children, pamphlets for adults.** Bitcoin material goes to the grown-ups.

3. **Teach custody, never price.** No pamphlet predicts a price or promises a return.

4. **Ask for nothing.** Give sats if you like. Never ask for money, an address or a signature.

5. **Point to the source.** Every pamphlet links the white paper so the reader can verify instead of trust.

6. **Respect the no.** One offer per person per season. A closed door stays closed.

## Add to your calendar

One calendar holds the fixed feasts and every chain feast for the next 24 months, each Turning included. A chain feast carries "(est.)" in its title until its date locks: once Hal's margin is under 12 hours and falls inside one day, and in any case three days before the block. A locked date never moves.
