I made myself a simple equation to convert reference stardates into standard dates while working on integrating information from The Orions: Book of Common Knowledge. (I assume that all pre-21st century dates are correct.)
If the refernce stardate is in the form A/BCDE.fghi, then the equation A.BC * 100 + 2000 will yield the appropriate date in the BCE/CE system. -- Steve 05:17, 21 February 2008 (UTC)
Problem with the BCE's[]
Hail,
BCE/CE Calendar year = A.BC x 100 + 2000, therefore A.BC = (Calendar year - 2000)/100
However, how do you compute for the first Olympics in 776 BC, compared to 776 AD, an entry into the "Annals of the Four Masters" according to Wikipedia?
776 = -12.24, but is that BC or AD?
The year 2012 is: A.BC = 2012 - 2000/100 A.BC = 0.12 ... correct for 2012 AD Stardate of 0/12, but what about 2012 BC?

- It looks like you might be missing the negative sign for BCE dates. Try these:
- 776 CE: (+776 − 2000)/100 = −12.24 → −12/24 (actually incorrect, see below)
- 776 BCE: (−776 − 2000)/100 = −27.76 → −27/76
- 2012 CE: (+2012 − 2000)/100 = 0.12 → 0/12
- 2012 BCE: (−2012 − 2000)/100 = −40.12 → −40/12
- However, a direct conversion of 776 CE to the stardate is actually −12/76. That is, the decade and year digits are copied directly in the "BC" slot. Your reversed formula doesn't account for this and so doesn't work for dates in the range 1 CE to 1999 CE.
- I hope that helps. -- BadCatMan (talk) 01:19, August 20, 2012 (UTC)
