The fourth Bitcoin halving is projected to occur on April 20, 2024, according to a Bitcoin Halving Date calculator. Previous halvings have been followed by significant growth in the cryptocurrency's market price. However, not all Bitcoin halving date calculators agree with this projection, with CoinWarz estimating the event to happen on April 19, 2024, and NiceHash predicting April 14, 2024.

Bitcoin's halving is a programmed event that reduces the block reward by half, lowering the rate at which new Bitcoins are generated. This mechanism helps to control inflation and maintain the total supply of Bitcoin at a maximum of 21,000,000 BTC. Historically, Bitcoin's price has rallied to record highs in the months following halving events, before correcting by more than 50% over the subsequent months.
