A little perspective

5 thousand years and Recorded-history interval have approximately the same time.

Measurements, assumptions & sources +

5 thousand years

Time conversions use a Julian year of exactly 365.25 days.

NIST — SI conversion factors

Recorded-history interval

A rounded 5,000-year reference interval, not a single worldwide starting date.

Defined examples — our methodology

The marked time is calibrated. Unmeasured illustration details are representative.

The two selected measurements are approximately equal.

How to read the visual

The labelled spans and stored measurements determine the scale; unmeasured illustration details do not.

  • Recorded-history interval is labelled reference interval; treat the displayed value as a comparison anchor rather than false precision.
