Bitcoin Halving Countdown (Live)
Roughly every four years, the reward miners earn for adding a block to the Bitcoin blockchain is cut in half. This live countdown estimates the time to the next halving from the current block height.

The block reward halves roughly every four years — a key driver of Bitcoin's supply schedule.
What is the Bitcoin halving?
New bitcoins enter circulation as a reward paid to miners for securing the network. About every 210,000 blocks — roughly every four years — that reward is cut in half in an event called the halving. It started at 50 BTC per block in 2009, dropped to 25, then 12.5, then 6.25, and at the 2024 halving fell to 3.125 BTC. The next halving, at block 1,050,000, will cut it again to 1.5625 BTC.
Why it matters
The halving is the mechanism behind Bitcoin's fixed supply of 21 million coins. By steadily slowing the rate at which new coins are created, it makes Bitcoin progressively scarcer — the feature its supporters point to as "digital gold." Historically, halvings have been followed by significant price cycles, though there's no guarantee past patterns repeat, and many other factors drive the price.
How this countdown works
Because blocks aren't mined on an exact schedule, the date is an estimate. This timer reads the current block height live and assumes an average of about ten minutes per block to project the halving date — so it shifts slightly as the network speeds up or slows down.
