Bitcoin halving countdown
About every 210,000 blocks Bitcoin mines, the reward miners get for producing a block is cut in half — roughly once every four years. That's the "halving". This page reads the current block height, works out how far it is to the next halving block (block 1,050,000) at about 10 minutes a block, and counts down live. One thing first: the halving halves the reward, not the price — two different things.
The block height comes from blockchain.info's public endpoint (live data, the chain is the source of truth). The time left is estimated as "blocks remaining × 10 minutes" — 10 minutes is just the protocol's target average block interval, and swings in hashrate can pull the halving weeks earlier or later, so the countdown is an estimate, not an exact moment. If the read fails, it falls back to a fixed estimated date, flagged above.
Rather than watch the countdown, get your account ready
The halving is a long-term story; what you can actually do isn't time the second it lands, but get your tools and your mindset ready in advance. If you're going to open an account, sign up to Binance with our invite code and shave your fees first.

What the halving actually cuts
New bitcoins are produced by "mining": miners package transactions and compete to record them, and whoever produces a block gets a block reward. The protocol says that every 210,000 blocks, this reward is cut in half. It began at 50 coins per block in 2009, then fell to 25, 12.5, 6.25; the 2024 halving happened at block 840,000 and dropped the reward to 3.125 coins; the next, at block 1,050,000, cuts it again to 1.5625. At about 10 minutes a block, that's roughly four years apart. This is a supply schedule hard-coded into the software that nobody can change — completely unlike a stock market, where supply is uncertain and shares can be issued or bought back at any time.
What people get led astray by is the "halving = moon" or "halving = crash" talk. All the halving directly changes is the rate at which new coins are produced: fewer new coins are mined each day, so the supply growth slows. Whether and when that pushes the price up depends on demand, the macro backdrop and market mood, and the price action around past halvings has differed every time — there's no inevitable pattern. So don't treat "halving" as "the price gets cut in half" — a price cut is market action, an entirely separate thing from the halving. To understand this properly, read the Bitcoin halving — far more useful than staring at a countdown.
We checked back: at the 2024 halving the community was wall-to-wall countdowns, plenty of people poised to "get on board" at that exact moment — and the day itself was flat, while the real volatility showed up over the months around it, in a direction far less one-sided than the memes suggested. So we built this tool to "show the rhythm" rather than "push you to trade": knowing roughly when the next one lands, and understanding it changes supply not price, matters far more than counting down to the second. Used with the long-term lens of the DCA calculator, it feels steadier.
