What a halving is
Every 210,000 blocks, the new bitcoin paid for each block is cut in half.
Each block pays the miner who finds it a fixed amount of new coins, the block subsidy, plus the fees of the transactions inside. The subsidy started at 50 BTC and halves every 210,000 blocks. Block 1,050,000 brings the fifth halving, cutting it from 3.125 BTC to 1.5625 BTC. The schedule is part of the consensus rules every node enforces, which is why the supply stops just short of 21 million.
What changes for miners
Their income from new coins halves overnight. Fees do not.
At the target of 144 blocks a day, new issuance drops from 450 BTC a day to 225 BTC. Fees are not part of the schedule, so they stay where the market puts them and become a larger share of what miners earn. Miners whose costs sit closest to their revenue switch machines off first. In the 60 days after each of the last four halvings, the 7-day average hashrate fell 11% to 25% below where it stood the day before.
How the date is estimated
Blocks left, times the average block time of the last two difficulty epochs.
We read the chain height from our own Bitcoin Core node and multiply the blocks left by the average time per block over the last two complete difficulty epochs (4,032 blocks, about four weeks), measured from our block data. The estimate moves as hashrate does. The last three eras took 1,319 days, 1,402 days and 1,440 days, all shorter than the 1,458 days that 210,000 blocks take at exactly 10 minutes, because blocks came faster than target while hashrate grew.
Past halvings and the 18 months after

Four halvings are a small sample, and each one met a different market. The table records what happened after them; it is not a forecast for the next one. Each multiple has been smaller than the one before. Dates and closes are UTC.
