Golden Number Cycle Position
Place a calendar year in the 19-year Metonic computus cycle using the standard medieval key goldenNumber = (year mod 19) + 1.
Description

- Year
- Calendar year (AD).
How Golden Number Cycle Position works
Place a calendar year in the 19-year Metonic computus cycle using the standard medieval key goldenNumber = (year mod 19) + 1. The tool evaluates the supplied inputs together and returns the named outputs below; it does not infer omitted operating conditions or change the units shown.1
- Golden number
- Golden number of the year (1-19).
- Metonic phase
- Zero-based position within the Metonic cycle (0-18).
- Years to restart
- Years until the phase resets to golden number 1.
Limitations and assumptions
- Script and manuscript evidence varies by language, region, institution, period, scribe, material, restoration, and cataloguing convention. A heuristic flag or score is not an authoritative date, hand attribution, reading, provenance, or conservation diagnosis.
- Use finite inputs in the displayed units and preserve more precision than the final presentation requires. Independently verify safety-critical, financial, compliance, or production decisions.
Alternative or Complementary approaches
Retain page images, scale, foliation, material, provenance, diplomatic transcription, uncertainty, and comparison exemplars; confirm conclusions with codicological context and specialist judgment.

- Easter Table Entry Decoder
Decode the computus row for a year into golden number and Easter Sunday date using Meeus's Gregorian algorithm or the classic Julian (Alexandrian) algorithm; Julian results are dates in the Julian calendar.

Look up the Julian computus epact = 11 x (golden number - 1) mod 30, i.e. the conventional age in days of the mean moon on 1 January, displayed as 30 when the residue is zero.
- Indiction Cycle Year Solver
Solve which calendar years begin a given indiction (1-15) under a chosen documented epoch - the Greek indiction turning each 1 September from 312, the Roman papal indiction each 25 December from 312, or the Bedan indiction each 1 January from 313 - using exact modulo-15 arithmetic.
