Space Year

The Space Year was a unit of time used by the Fourth Doctor when he recounted to Davros how a fleet from the planet Hyperion intercepted a Dalek invasion of Venus in Space Year 17,000. (DW: Genesis of the Daleks)


 * How Space Years relate to Earth years is unknown, though one account suggests that the Dalek invasion of Venus in Space Year 17'000 coincided with the 22nd century Dalek invasion of Earth.
