Calendar of the Second Terran Empire
The Second Terran Empire counted years according to the Holocene Era (HE), the start of which was arbitrarily fixed at 12,000 BCE. Thus, CE dates can be found by subtracting 10,000 from HE dates; i.e. 20,724 HE = 10,724 CE.
The Second Empire year is 400 standard days. The year is divided into ten months of 4 tendays each.
