# Calendar measure comparison

The original three Keys share one schematic calibration. Different output counts carry the same modeled day-volume.

| Key | Exact factor | Output year measure | Count from 12558 | Modeled volume |
|---|---:|---:|---:|---:|
| Priestly | 25/23 | 336 | 13650 | 4586400 |
| Prophetic | 70/69 | 360 | 12740 | 4586400 |
| Enochian | 300/299 | 364 | 12600 | 4586400 |

Placement still requires a declared pivot and source route. These schematic year measures do not identify an exact observed tropical year. The original default inventory remains E/P/J; the Sothic H and exact-K 365-day G extensions retain their separate status.
