Gregorian Chant or Julian Fries
I recently got my 2006 calendar. I always have two calendars on the wall to allow me to see where I’ve been and look where I’m going. The life of a planner. I had always heard of the Julian date or the Gregorian calendar and wondered what the difference was and why there were two names for what appears to be the same thing. Well after a little research here it is.
The Gregorian calendar was proposed by Aloysius Lilius, a Neapolitan doctor and was decreed by Pope Gregory XIII, hence the name. Aloysius Lilius wrote Compendium of the New Plan for the Restitution of the Calendar which described the process for the Gregorian calendar. Unfortunately he died in 1576 and his compendium was presented to Pope Gregory by his brother. It was adopted in 1582.
It replaced the Julian calendar. The Julian calendar was introduced by Julius Caesar in 46 BC and took affect in one year later. It was chosen after Caesar had consulted with the Alexandrian astronomer Sosigenes.
Both calendars are designed on the tropical year. It has 365 days divided into 12 months with a leap year added in every four years. The average Julian year was 365.25 days long. This however added too many leap days and caused a gain of one day every 128 years. Julius Caesar is said to have known about the gain of days but was not concerned (probably because who thought in terms of that amount of time). If you do the math, it ends up being 1628 years between the implementation of the Julian Calendar and Gregorian calendar. With one day for every 128 years, it could have been 12.7 days change over that period. If we were still on the Julian system, we would have changed 16 days.
The Gregorian calendar fixes the float issue with some complex mathematical formula based on 400 year cycles and adding days when it was implemented. The implementation of the Gregorian calendar actually caused riots because people though that they were being cheated into giving up 11 days of rent to their land lords.
Now Gregorian chants were named for Pope Gregory I and have nothing to do with the calendar other than share a name. Julian fries are named for the way they are cut and although there is probably some connection to Julius Caesar, I have not been able to ferret it out. Just look for the connections.

I couldn't help but add to the "quest for knowledge" here - not to critique, but just because it brought a smile.
Interestingly enough, there is a Julian calendar, and a Julian date, but the Julian dates are not found on a Julian calendar. Julian dates are actually used in data processing, where 2007059 is the 59th day of the year, 2007, or Feb. 28th. It uses fewer digits for storage of a given date (compared to 2007-02-28, for instance). So there's something else to consider, I guess.
(btw, if you were a real data geek, you would say that Julian dates were "less precise" than regular date notation. It doesn't mean that they tell the date any less accurately, but simply that "precision" is a measure of the number of characters or digits used. So by using Julian dates, you can be "less precise" while remaining "just as accurate." Isn't language fun?....)
Now, I hate to break your bubble on the next one, but the ghost of Julia Childs wouldn't let me let this one slide. The fries you were talking about (or any other foodstuff, for that matter) are Julienne, not Julian. You can see this demonstrated here. It was originally French in nature - Wikipedia says it's related to a French chef over here, but I'd want more research before I trusted Wikipedia for much.
Anyway, I'm glad I found you. Ted said you were a reader of mine, but I'd no idea you'd been blogging yourself for so long. Now I need to go back and catch up on all of your stuff!
peace -
