Bitcoin Halving Countdown
Track the next Bitcoin halving: the target block, blocks remaining and a live countdown based on the current chain height.

The date is a projection from the average block time, not a schedule. Real halvings arrive when the block is mined, which can drift by days.
How the Bitcoin Halving Countdown works
Bitcoin cuts its block subsidy in half every 210,000 blocks. The countdown takes the current chain height, finds the next multiple of 210,000, and multiplies the blocks in between by the average block time. Because block times vary with hash rate, the date moves as the network speeds up or slows down.
Formula
Epoch = floor(Block height ÷ 210,000)Next halving block = (Epoch + 1) × 210,000Blocks remaining = Next halving block − Block heightEstimated time = Blocks remaining × Average block timeBlock reward = 50 ÷ 2^Epoch

Frequently asked questions
What is the Bitcoin halving?
Every 210,000 blocks the reward paid to miners for each block is cut in half. It is the mechanism that caps total supply at 21 million and makes new issuance fall over time.
How accurate is the countdown date?
It is an estimate. Blocks average ten minutes but arrive randomly, and the difficulty adjustment only corrects the average every two weeks. Expect the projected date to shift by a few days as the halving approaches.
Where does the block height come from?
From the chain data provider configured in the plugin settings, cached for a short period. If no provider is available the page says the countdown is unavailable rather than showing a stale or invented height.
What happens when the reward reaches zero?
Once the subsidy falls below one satoshi it stops entirely, which is projected for some time after 2140. From then on miners are paid only from transaction fees.
