When Was the Third Bitcoin Halving?

The third Bitcoin halving occurred on May 11, 2020, at 09:23:43 UTC. This event transpired when the network reached its 630,000th block, the first block to have the new mining reward of 6.25 bitcoins per block, down from the previous block's reward of 12.5 bitcoins.

In a nod to tradition, the miner of block number 629,999 included a coinbase message that mirrored the message from the genesis block. It was originally intended for the halving block. The message reads, NYTimes 09/Apr/2020 With $2.3T Injection, Fed's Plan Far Exceeds 2008 Rescue. This message refers to a New York Times article about the Federal Reserve's unprecedented fiscal stimulus plan to combat the economic fallout caused by the COVID-19 pandemic.
