BTC: Signed Daily Block Interval — 14-Day Arithmetic Mean

Bitcoin Signed Daily Block Interval — 14-Day Arithmetic Mean was 605.31 seconds on 7 Nov 2026 (latest daily value).

The 14-day arithmetic mean of daily average signed block intervals, in seconds.

Why use it. Follow the recent pace of block production with each UTC day weighted equally. How to read it. Higher values mean blocks arrived more slowly on average over the 14 days, lower values faster. Each day counts equally regardless of how many blocks it had, so this is not the block-weighted mean of all intervals in the window. Negative header intervals are preserved rather than removed. A missing or partial day invalidates the window. Original clocks and weakest-input finality apply.

Calculation. Average exactly 14 adjacent complete daily signed block-interval means, including the displayed day. Each daily mean uses child header time minus exact parent header time for that day's blocks, at its existing daily precision. Guarded cumulative arithmetic gives 40-significant-digit Decimal output.
