Here are the approximate dates of all the past Bitcoin halvings:
- First Halving: November 28, 2012
- Block 210,000
- Block reward reduced from 50 BTC to 25 BTC
- Second Halving: July 9, 2016
- Block 420,000
- Block reward reduced from 25 BTC to 12.5 BTC
- Third Halving: May 11, 2020
- Block 630,000
- Block reward reduced from 12.5 BTC to 6.25 BTC
The next halving, expected in April 2024 (Block 840,000), will reduce the block reward from 6.25 BTC to 3.125 BTC. These dates are based on the approximate time it takes to mine 210,000 blocks, which is about four years, but the exact timing can vary slightly depending on network conditions.
