Different calendar counts, one schematic measure
The three calendar Keys connect different year counts through one declared measure. Write E=25/23 for the Priestly Key, P=70/69 for the Prophetic Key, and J=300/299 for the Enochian Key. Their matching calendar lengths satisfy 336E=360P=364J=8400/23. Multiplying a span by a Key therefore changes its count while preserving the same modeled day-volume when the corresponding unit accompanies the result.
For the shared span 12558, the outputs are 13650, 12740 and 12600. Multiplying these respectively by 336, 360 and 364 gives 4586400 in every case. This existing calibration explains why different numerical totals can belong to one mathematical family.
Unit labels also matter when separate components receive different Keys. The inherited comparison built from the 299|161 partition gives 300|175 under J on the first part and E on the second. With their matching units, 300×364+175×336=168000. Swapping the units changes that volume to 164500 although the numerical sum remains 475.
The connection is exact but conditional: it describes a schematic calendar realization, not proof that a chronology literally elapsed in mixed historical calendars. A complete comparison consequently carries both the number and its declared unit. Equal numbers without matching units, and unequal numbers with matching measures, tell different stories.
