Bitcoin Halving Countdown

Last reviewed: 2026-09-22

A live countdown to the next Bitcoin halving - the moment the reward for mining a new Bitcoin block is cut in half. See the estimated date and time in your own time zone, how many blocks are left, the current block height, how the block reward will change, and every halving so far.

How it's calculated

Bitcoin halvings are defined by block height, not by a calendar date: every 210,000 blocks the reward for each new block is halved. The 5th halving happens at block 1,050,000, when the reward drops from 3.125 to 1.5625 BTC.

Because new blocks are found roughly - but not exactly - every 10 minutes, the date of a halving can only be estimated. This tool takes the latest block (its height and the time it was mined), counts how many blocks are still missing, and multiplies them by Bitcoin's target of 10 minutes per block:

Estimated halving time = time of the latest block + remaining blocks × 10 minutes

The current block height comes from mempool.space, a public Bitcoin block explorer, and is refreshed about every 10 minutes. If that data is temporarily unavailable, the page says so and estimates the height from the last known block instead. Since blocks usually arrive a little faster than every 10 minutes, the real halving often comes a few days earlier than a long-range estimate - the date moves slightly as it gets closer, which is normal.

Worked example

On 22 September 2026, the latest block was number 968,165. That left 1,050,000 − 968,165 = 81,835 blocks until the 5th halving. At 10 minutes per block that is about 818,350 minutes, or roughly 568 days - which puts the estimated halving in mid-April 2028. After it, miners will receive 1.5625 BTC per block instead of 3.125 BTC; with about 144 blocks a day, the number of new bitcoins created daily falls from about 450 to about 225.

Frequently asked questions

What is the Bitcoin halving?

It is a rule built into Bitcoin itself: every 210,000 blocks (about every four years), the amount of new bitcoin paid to miners for each block is cut in half. It started at 50 BTC per block in 2009 and is 3.125 BTC since April 2024.

Why does the estimated date change?

Because the halving happens at a fixed block number, not a fixed date, and blocks are not found at exactly 10-minute intervals. Each new block updates the estimate; the closer the halving gets, the more precise it becomes.

What happens to the total supply of bitcoin?

Halvings are what cap the supply at just under 21 million bitcoin. Each halving slows down how fast new coins are created, and after roughly 32 halvings (around the year 2140) the block reward reaches zero.

Does the halving make the bitcoin price go up?

Nobody can say. Past halvings were followed by very different market phases, and many other factors move the price. This tool only counts down to the event itself - it is not an investment recommendation.

Where does the block height come from?

From mempool.space, a public and widely used Bitcoin block explorer, with blockstream.info as a backup. Our server asks for it at most every 10 minutes; your browser does not contact these services.
