Bitcoin Halving Countdown
The block height is read live from public block explorers and refreshed every minute. The date is an estimate: blocks do not arrive on a fixed clock.

Formula
Next halving block = 210,000 × (number of past halvings + 1) = 1,050,000
Blocks left = 1,050,000 − current block height
Estimated time = blocks left × 10 minutes (protocol target)
Block reward after the halving = 3.125 ÷ 2 = 1.5625 BTC
The 210,000-block interval and the 50 BTC starting reward are fixed in Bitcoin's consensus rules. Actual block times vary with mining power; difficulty is adjusted every 2,016 blocks to pull the average back to 10 minutes, so the estimate moves by days or weeks.

Frequently asked questions
When is the next Bitcoin halving?
At block 1,050,000. With 10-minute blocks that lands in 2028; the countdown above shows the current estimate, which shifts as real block times vary.
What changes at the halving?
The new bitcoin paid to miners per block halves from 3.125 to 1.5625 BTC. Transaction fees paid to miners are not affected. The total supply stays capped just under 21 million BTC.
Does the price rise after a halving?
There have been only four halvings, and each happened in a different market. This page tracks the schedule only and makes no price prediction.
Why is the date only an estimate?
The halving is set by block height, not by calendar date. Blocks arrive on average every 10 minutes but sometimes faster or slower, so the estimated date moves.
How we calculate and limits
Block height: mempool.space and blockstream.info public APIs (live in your browser). Halving interval and starting reward: Bitcoin Core consensus parameters (nSubsidyHalvingInterval = 210,000). Past dates are the UTC dates of blocks 210,000, 420,000, 630,000 and 840,000. Not investment advice.
