Bitcoin Halving Schedule: Every Halving from Genesis to 2140 (Data + API)
The complete Bitcoin halving schedule — block height, subsidy, date, cumulative issuance and percent of the 21M cap for every halving.
Quick answer
Bitcoin's block subsidy halves every 210,000 blocks (~4 years), stepping down the rate new bitcoin is issued until it reaches zero around 2140 — capping supply at 21 million. The next halving (#5) is projected around 2028-04-17 at block 1,050,000, cutting the subsidy to 1.5625 BTC.

Past halving dates are historical; future dates are projected at ~10-minute blocks and will drift with real network timing. Subsidy is satoshi-accurate (the last non-zero subsidy era ends near 2140). Pairs with the live network vitals and difficulty history.
