The chart lines up each cycle by weeks from its halving. Hover, tap, or use the ← → keys to step through weeks; the box under the chart shows the 2024 cycle (Pro shows every cycle), and the heatmap outlines the matching calendar month for every cycle. The 2012 cycle is chart-only and is off by default.
A Bitcoin halving chart lines up each cycle by the time since its own halving instead of by calendar date, so the cycles can be read against each other. The four halvings so far were on 28 November 2012 (block 210,000), 9 July 2016 (block 420,000), 11 May 2020 (block 630,000) and 20 April 2024 (block 840,000). The next is at block 1,050,000, expected around spring 2028. This chart plots weeks from the halving, starting 500 days before it, with either the halving-day price or the price 500 days before set to 100. The free view shows the 2024 cycle with a live price overlay. Pro adds the 2012, 2016 and 2020 cycles.
Daily numbers for all four cycles are on the cycle tracker; dates, blocks and rewards are on halving dates and FAQ.
The "four year" in the four-year cycle is a block count, not a date: the reward halves every 210,000 blocks, which has taken about four years so far. A linear week-by-week chart keeps that structure visible. Each colour is one cycle, week 0 is the halving week, and negative weeks are the run-up. Turn on Live price to draw today's price onto the 2024 line and see where it sits against the earlier cycles at the same week. Four cycles is a small sample, and the chart describes what happened. It does not say what happens next.
See how many days since the halving, or the numbers at today's day count.
Scroll the wheel over the chart (or pinch on a touchscreen) to zoom in on a stretch of weeks, drag to move along it, and double-click, press Reset or use the + and − buttons or keys to change the zoom. The price axis re-fits to what you can see. The heatmap and the box under the chart follow the week you point at.
The dotted line re-draws the percentage shape of the cycle(s) you pick, starting from today's price and scaled by the amplitude (log scale). "Decay" shrinks the move the way gains shrank between the 2016, 2020 and 2024 cycles (three cycles, so a small sample). It assumes today's price holds until 500 days before the next halving. It is a what-if built from past shapes, not a forecast or a price target.
Weekly closes from a public daily BTC/USD series. Sep 21 and Sep 30 2026 closes come from published sources. After Oct 7 2026 the chart uses live daily prices (Coinbase, with Kraken as backup). Halvings: 2012-11-28, 2016-07-09, 2020-05-11, 2024-04-20; next about 2028-04-13 (estimated from the live block height, moves with block time).
Yes. The 2024 cycle, the live price overlay, both bases (price 500 days before the halving = 100, or halving-day price = 100), zoom and pan are free. Pro adds every earlier cycle, the illustrative 2028 path, the Price (USD) view and the full heatmap, from $19 a month or $149 a year, cancel any time.
A radar chart wraps the cycle around a circle. A halving chart like this one is linear: time runs left to right in weeks from the halving, so the same week in two cycles sits directly above each other.
No. It shows what earlier cycles did. The illustrative 2028 path in Pro is a what-if built from past cycle shapes, not a forecast.
Every 210,000 blocks, roughly every four years, the reward miners get for a new block is cut in half. It has happened four times: in 2012, 2016, 2020 and 2024. The 2024 halving cut the reward from 6.25 to 3.125 BTC.
The fifth halving happens at block 1,050,000. At about ten minutes per block, that is expected around spring 2028. The exact date depends on how fast blocks are found.
Line each cycle up by time since its own halving, not by calendar date, and put the prices on a common base. Bitcoin halving cycles plots every cycle by weeks from the halving, starting 500 days before it, with either the halving-day price or the price 500 days before the halving set to 100.
The cycle tracker at bitcoinhalving.info/cycle-tracker answers this daily, comparing each cycle at the same number of days after its halving. On the chart, turning on Live price draws the current price on the 2024 line, so you can see week by week whether it sits above or below where the 2016 and 2020 cycles were.
No. It re-draws the percentage shape of the past cycles you choose, starting from today's price. It is a what-if built from history, not a forecast or a price target.
The 2024 cycle, the live price overlay, both bases, zoom and pan are free. Pro adds every earlier cycle, the illustrative 2028 path, the Price (USD) view and the full heatmap, from $19 a month or $149 a year.
