CANONICAL NORMATIVE
DYPCLT
The hierarchical temporal address of LXKeys.
DYPCLT means Decade, Year, Period, Cycle, LX and Time. The conventional epoch is 1 April 2023.
One period contains 72 LX, distributed across eight cycles of nine LX. One LXKeys year contains seven periods, and one decade contains seven years. D and Y start at zero; P, C, L and T start at one.
For index n, decomposition uses Euclidean division over 3528, 504 and 72. For negative indices, Euclidean remainder stays positive, preserving deterministic DYPCLT addressing on both sides of the epoch.
