I was looking at a small video clip we put up on You Tube the other day.

Anno Domini was the first of these to appear. This was supposedly in part a response to advice Diocletian received at the oracle of Apollo at Didyma. Previous to this, he had purportedly only advocated banning Christians from such things as the military and ruling body in hopes that would appease the gods. Afterward, he switched to an escalating policy of persecution to try to get Christians to worship the Roman gods. When this sort of thing was ineffective, they progressed to arresting and torturing Christians, starting with the leaders.

This method of convincing people to worship the Roman gods ended up being an amazing failure and the persecution appears to have only continued after AD in the Eastern half of the empire under Galerius and Maximinus. Finally, in April of AD , by imperial decree , the Great persecution was put to an end even in the East.

A single number equal to the number of days since January 0, in the proleptic ISO calendar specifying use of the Gregorian calendar. In Octave, they document.

The gregorian calender does not use a year zero. But Matlab and Octave refer to the year zero. Does this mean that they refer to year -1 BC, as in the astronomical year numbering? Days before “October 15, ” are “wrong by as much as eleven days”, according to the octave manual, which is considerably smaller than a complete year. So I’m trying to sort out this ambiguity.
