Behind the scenes
This year obviously describes the events of 1945 AD. However in relation to 14512 BG (Battle of Englichannel) identified with 1588 AD, only 257 years pass, while in reality the gap between those events was 1945-1588=357 years; one century more.

Perhaps the date 14255 is an error, and should be corrected to 14155 BG
