Bitcoin Halving Countdown
Calculated live from the current Bitcoin block height and the network's ~10 minute average block time.
What is the Bitcoin Halving?
Roughly every four years, or every 210,000 blocks, Bitcoin's mining reward is cut in half. This built-in schedule controls Bitcoin's supply and is a core part of its scarcity model. This countdown reads the live block height from the Bitcoin network and estimates the halving date using the average 10-minute block time; the real date can shift by a few days depending on network hash rate.
Frequently Asked Questions
When is the next Bitcoin halving?
The estimated date shown above is calculated live from the current block height plus the number of blocks remaining until the next halving, using the network's average 10-minute block time.
Why does the estimated date sometimes shift?
Bitcoin blocks are not produced at exactly 10 minutes; the actual rate depends on network hash rate, so the estimate can move by a few days as blocks are mined faster or slower than average.
What happens to miners after a halving?
The block subsidy miners receive is cut in half, so mining profitability depends more heavily on transaction fees and the price of Bitcoin at the time.
How many halvings will Bitcoin have in total?
Bitcoin is designed to have 64 halvings before the block subsidy reaches zero, expected to happen around the year 2140.
Is the Bitcoin halving countdown free to check?
Yes, this countdown is completely free, updates from live Bitcoin block height, and requires no signup.
How many days until the next Bitcoin halving?
The estimated days and date until the next halving are calculated live above from the current block height and the network's average block time.
