Halving Countdown

Watch the next Bitcoin, Litecoin, and Bitcoin Cash halvings approach — driven by live block height, with the date always labelled an estimate.

Protocol mechanic — not a price event

Next halving countdown

A halving is a protocol supply mechanic, not a price event. Nothing here is a prediction, a buy/sell signal, or financial advice. The block height is the fact; the date is an ESTIMATE that depends on real-world block timing and cannot be known exactly. Education only. Sources are public, read-only block explorers — this widget never touches your wallet, keys, or funds.

Block height is certain; the date is an estimate driven by real block timing. Not financial advice.

A note on Dash: it is nota true halving — it reduces the block reward by roughly 7.14% about every 210,240 blocks (~383 days), a gradual taper rather than a one-step halving, so we don't list it as a countdown tab.

What is a halving, and why does it matter?
A halving is a rule baked into the protocol: roughly every 210,000 blocks (about four years for Bitcoin), the reward paid to miners for adding a block is cut in half. It is the mechanism that enforces a fixed, predictable supply schedule — Bitcoin will only ever issue 21,000,000 coins. It is a supply mechanic; it says nothing about price, and we make no claim that it does.
Why is the date only an estimate?
The halving triggers at a fixed block height, which is certain. But blocks don't arrive on a perfect clock — miners find them a little faster or slower than the protocol's target time depending on how much hashing power is online. We estimate the date by multiplying the blocks remaining by the target block time, so the date can shift by days or weeks as real conditions change. That's why every date here carries an ESTIMATE badge.
