Bitcoin halving-cycle coordinate system

Overlay lows as negative (-) day offsets and highs as positive (+) day offsets from each halving. This shared axis makes the areas where each season's lows and highs cluster easy to compare.

↔ Scroll the chart horizontally to explore the full range.

Loading the interactive coordinates. Every value is also available in the table below.

  • Low: negative offset from halving
  • Halving baseline
  • High: positive offset from halving
  • Current position
  • Bear zone: before -542 / after +548
  • Low-to-high progression

How to read

Three ways to read the numbers

The interface separates schedule, progress, and data status from price narratives.

Blocks are the trigger

A halving occurs at its target block height, not at a reserved calendar time.

The date can move

When blocks arrive faster or slower than ten minutes, the estimated time moves too.

Past and forecast differ

Badges, dashed lines, and plain-language notes distinguish provisional and forecast data.

FAQ

Frequently asked questions

What is a Bitcoin halving?

It is the protocol rule that cuts the block subsidy in half roughly every 210,000 blocks.

Why is the next halving not an exact date?

The event occurs at a target block height, while actual block intervals are not fixed at ten minutes.

How is cycle progress calculated?

Subtract the fourth-halving height of 840,000 from the current height, then divide by 210,000 blocks.

How are cycle lows and highs selected?

The local MVP uses provisional UTC date offsets. Final definitions and primary sources still require operator approval.

Are forecast ranges confirmed dates?

No. They are simple reference windows created by carrying the earliest and latest past observations into season five.
