Coligny Calendar (Gaulish) (科利尼曆)

The Coligny calendar — a REAL Gaulish bronze tablet found near Coligny, Ain in 1897, inscribed in the Gaulish language with Roman capitals and dated to the late 2nd century CE. It is the longest surviving text in Gaulish: five years, 62 months, ~2,200 day-cells, each with a peg hole (it was a parapegma, advanced one peg per day). Unlike the modern Celtic Tree Calendar, this is an attested artifact — and this reading is deliberately honest about the limits of what it can tell you. It gives the attested structure (the twelve months with their MAT/ANM labels and 29/30-day lengths, the ATENOUX fortnight split, the five-year lustrum and its two intercalary months) and computes the TRUE LUNATION at your birth — your day within the lunar cycle and which side of the ATENOUX midpoint you fall on, which is astronomy rather than reconstruction. It does NOT tell you your Gaulish birth month: no epoch survives on the tablet, and published reconstructions place the first month anywhere from late April to November, so a single month name would be arbitrary precision. Instead the competing reconstructions are shown side by side. MAT/ANM are given with BOTH scholarly readings — the standard edition's 'complete/incomplete' (which the near-perfect correlation with month length supports) and the popular 'auspicious/inauspicious'. Note the calendar was never used for birth readings; no Celtic natal astrology is attested at all, so any personal reading is a modern overlay on a genuine artifact.
