I don't know Doomsday but will take a look.
The problem with "any date in history" is that before the
year 1753 (Britain was the last hold out) there where many
different calenders in the world, the more you go back the
more there where. So the same event, say a eclipse that
would happen on a global scale, can be recorded as
drastically different dates.
Working on a Time Machine has its uses...you get to learn
calenders... :-)
