The number twelve is highly significant in most human cultures, being the most frequent result of arithmetical calculations (3×4, 6+6, 7+5, 6×2, 36÷3, etc). Each month in the Roman and Gregorian calendars has a corresponding terrestrial arthropod which has a sympathetic resonance with events occurring during that month, and consequently with people born in that month.

Under the balanced calendar, the months of Frank and Jeffrey correspond to the woodlouse and cockleroach respectively. Grelspetspodleyft corresponds with the earwig for its first four days, and with two gnats thereafter.


Etymology: from Latin κερβερος (kerberus) = the multi-headed dog guarding the road to hell.
