2548

Winter or Spring

 * 20th June - Latest possible date for the Battle of Bellatrix. Dalek forces engage the Earth Alliance's Spacefleet at Bellatrix. At the end of the battle, Admiral Summerfield's battleship, the Tisiphone, falls into a spatio-temporal rift and is transported to 1963 Earth.
 * Date is conjecture, based on Benny being 7 when her father disappeared (NA: Return of the Living Dad), 8 when her mother died (BFBS:The Extinction Event), that the two events were six months apart (BFBS:' Missing Adventures:The Evacuation of...'), and that Benny's birthday is 21st June (BFBS: Just War)).

Summer or Fall

 * After 21st June but before 21st December- Daleks attack the Earth colony of Beta Caprisis. Claire Summerfield is killed. Survivors of the attack are evacuated to a space station aboard the luxury liner Star of Lucknow.
 * This event must take place within six months of Benny's eighth birthday, 21st June 2548.
