Next Bitcoin halving
A block-height milestone, not a fixed date. Track the next reduction in newly issued bitcoin.

Estimate needs refreshing. The countdown does not confirm that the halving block has been mined. Reload the page to check the height.
Assumption: 10 minutes per block. Blocks arrive at irregular intervals: this date can move earlier or later and is not a guaranteed deadline.

Each cycle spans 210,000 blocks. Neither the height nor the remaining blocks are simulated by the countdown.
What does the halving change?
Every 210,000 blocks, Bitcoin halves the subsidy paid to miners, rounded down to whole satoshis. This subsidy creates new bitcoin; transaction fees are added separately and are not halved.
The next milestone is calculated from the observed height, then rolls to the following cycle once that milestone is reached. An old observation does not confirm the current network cycle.

Estimated date = observation time + remaining blocks × 600 seconds. This is the time the height was retrieved, not the timestamp of the last block. Actual pace depends on hashrate and difficulty adjustments.
Server-side retrieval: mempool.space, with Blockstream as fallback. No explorer requests are made from your browser.
Protocol information, not a price forecast or financial advice. A halving does not guarantee a rise in bitcoin’s price.
