## How Often Does Bitcoin Adjust Its Mining Difficulty?

Bitcoin adjusts its mining difficulty approximately every two weeks, or more precisely, every 2,016 blocks. The protocol calculates the time it took to mine the previous 2,016 blocks.

If the average block time was faster than the target of 10 minutes, the difficulty increases. If it was slower, the difficulty decreases.

This predictable, periodic adjustment ensures the average block time remains consistent, regardless of the number of miners.

## Dictionary

### [Average Block Time](https://learn.greeks.live/area/average-block-time/?utm_source=crypto.greeks.live&utm_medium=referral&utm_campaign=satellite)

Metric ⎊ Average Block Time is the mean duration required for a Proof-of-Work or Proof-of-Stake network to successfully validate and append a new block to the canonical chain, serving as a primary indicator of network throughput and transaction finality speed.
