Bitcoin halving countdown
Current network height: block 973,019 of 1,050,000 · updated 2026-10-25
What is the halving?
Roughly every four years (exactly every 210,000 blocks), the reward miners receive per block is cut in half. It is Bitcoin's fixed monetary policy, written in code since day one: supply issuance keeps shrinking until it stops entirely around the year 2140. In the next halving, at block 1,050,000, the reward drops from 3.125 to 1.5625 BTC per block — daily issuance falls from roughly 450 to 225 BTC.
Why the date is an estimate
The halving happens at an exact block height, not an exact date. Blocks are mined every ~10 minutes on average, but the real pace varies with network hashrate — so the date moves. This page recalculates hourly from the current network height; the block number is certain, the date is not.
Past halvings
| Block | Date | Reward change |
|---|---|---|
| 210,000 | 2012-11-28 | 50 → 25 BTC |
| 420,000 | 2016-07-09 | 25 → 12.5 BTC |
| 630,000 | 2020-05-11 | 12.5 → 6.25 BTC |
| 840,000 | 2024-04-20 | 6.25 → 3.125 BTC |
Other milestones, same mechanism
The same live chain height that powers this countdown also feeds three other pages: the block 1,000,000 countdown, 96% of supply issued, and the next difficulty adjustment — which in turn sets how much it costs to get a transaction mined, see Bitcoin fees today.
What it means for the cycle
Historically, halvings have marked the rhythm of Bitcoin's market cycles — each one preceded a bull phase, though with diminishing intensity and no guarantee of repetition. Rather than predicting, we measure: the NodeWitness cycle Score tracks where the market actually is, for free and with a public methodology.
Whether that rhythm still holds is the question behind is Bitcoin’s four-year cycle dead?, and the tops and bottoms that followed each halving are documented with dates. You can also see how the Score moved around the last one in April 2024 in the Score history.
