View Full Version : "The Ages of Mankind" from 6th ed rulebook

Hi all

I've just finished reading the section of the 6th ed rulebook called "The Ages of Mankind" (p168-177).

Most of the entries are dated as three digits followed by a M and two further digits. I have assumed that the M and two digits denotes the millenia and the first three digits are the year of that millenia. E.g. 888.M41 is the 888th year of the 41st Millenium - in other word,s the year 40,888.

But at the end of page 175 onwards, a further three digits are introduced to the entries, e.g. 138997.M41, 221997.M41 884999.M41.

I have assumed they are a further subslice of time, and so would refer to the months or even days of the year that follows but I cannot make head nor tails of what exactly they mean.

Does anyone have any more precise ideas?

thanks!

p. 406 The march of Time

Basically, the first digit indicates how reliable the date is, the next 3 digits are the year fraction, and the last 3 digits the millenium fraction

They are 1000th's of a year as part of the administratum's record keeping. 221 would be the 221st unit of the year 997 of the Millennium 41. Using the Solar year as the basis each segment is ~8.76 hours long. It's used pretty much only for official purposes.

EDIT: It doesn't look like the examples given in the OP include the additional accuracy code, they'd be 7 numbers long then.

thanks for the quick replies guys! that'll teach me not read the entire book before posting!

one more question to Hellebore: what does OP mean?

just thought i'd add that i'm very much enjoying reading this book

Original Post/Poster.

That particular form of dating has been in 40k since Rogue Trader was released. In fact the march of time section Cthell points to is probably paraphrased or a direct quote of the original text.

And conveniently enough roughly the length of a citizen's work-shift :p

Yup. Work 8.76 hours, toilet break. Work 8.76 hours. Toilet Break. Work 8.76 hours. Quick nap or toilet break. Work 8.76 hours. Tea break. Work 8.76 hours.

Nah.

8 hours of work (following the finest traditions of ancient terra! Praise the ancestors for selecting an appropriate minimum!) .76 hours of personal time
another 8 hours of work, another .76 hours of personal time.
6 hours of sleep.

And the rest?

Praying to the emperor of course!

I've always found the calendar-weirdness a great piece of fluff. We call it an Imperium, but co-ordinating a 'standard clock' is nigh-impossible to the point where the system has given up. We just don't know if some events are correlated in time between systems.

I thought that was really cool.

Terra should put aside a specific type of psyker, and then throw them into the sacrificial machines at regular intervals. This could change the flavor of the Astronomicon in ways that could allow distant worlds to set their clocks. A more clever thing could be some type of morse code. (100,000 pyrokinetics? A dash. 100,000 random psykers? a space. 100,000 fortune tellers? A dot)

This was actually the basis for the Moirae Schism that caused a lot of contention in the AM and formed the Sons of Medusa. Essentially an AM sect was using micro fluctuations in the Astronomicon's signal strength to predict the future. A good chunk of marines from the Iron Hands and their successors were converted to the Moirae view and were exiled from their chapters to become the Sons of Medusa.

The following is from the last core rulebook. Let's take 0150935M41.

M41 obviously means the 41st millennium.

The three digits preceding M41 indicate the specific year being referenced within that millennium. In this case, the year in question is 935, or 40,935. This year would show as 935M41 in the Imperial Calendar.

The next three digits are the year fraction, ranging from 001 to 000. In this case, 150 expresses that we're less than 1/6 of the way through the year 935.

The first digit is the dating reference or "check number". The best way to explain it is its calendar accuracy relative to the Earth standard. So, for instance...

- 0 or 1: would indicate an event that happened within the Sol system.
- 2: (direct) an event whose source was in direct psychic contract with Terra when the date reference was made.
- 3: (indirect) an event whose source was in direct psychic contract with a class 2 source, not Terra, when the date reference was made.
- 4: (corroborated) an event whose source was in direct psychic contract with a class 3 source when the date reference was made.
- 5: (sub-corroborated) as per 4, but in direct contact with any corroborated source.
- 6: (non-referenced/1 year) no psychic contact with a class 1-5 source when the reference was made. The unsourced period is less than one standard year.
- 7: (non-referenced/10 years) as per 6, but with an unsourced period of 1-10 years.
- 8: (non-referenced/> 10 years)
- 9: an approximated date with no fixed coordinates, or a date drawn from non-Imperially dated references.

As such, 0150935M41 would mean an event occurring on Terra or within its solar system. By contrast, 9150935M41 would mean we are referencing an event that occurred less than 1/6 of the way through the year 40,935, but which cannot be corroborated with any real degree of accuracy... or came from a world that doesn't use Imperial dating.

Surely you mean 9150953M41 ?

Thanks! I didn't know that. It's a different flavor from what I was thinking, but I betcha the signal from the Astronomicon would be more useful than leaves of tea in a teacup!

You, sir, are a gentleman. And now, I'm off to edit.
