Is there a typographic or historical explanation for why multi-digit numbers get a comma (or space or point) inserted to separate groups of three digits, but not years? If separating number groups wasn’t in practice at the time (the year 1000), it clearly wasn’t in practice for numbers in general. When it did come into being (when?), why didn’t it apply to the year? Was it theological? Was it because the year is not an adjective? ---

Four digit numbers usually don’t get commas in the first place. Most style guides tell you leave them out until the numbers get to five digits. ---

June 13, 2,008. Looks pretty funky. Is it the 13th, or 13.2? 06/13/2,008. 13/06/2,008 for you Euros. Still pretty pointless. ---

Can’t recall what was done with more digits, or recall whether I’ve seen them. Of course a quick look at the Wikipedia article on _Foundation_ shows commas in all the five digit years. :smack: ---

It could be different. We could be using [Indian numeric separators](http://en.wikipedia.org/wiki/Indian_numbering_system): 10 100 1000 10,000 1,00,000 (100 thousand; 1 _lakh_) 10,00,000 (10 _lakh_) 1,00,00,000 (100 _lakh_; 1 _crore_) ---

Years are a count from some event—it’s been five years since The Big Guy was born. It’s been 142 years since the Grand Shuffle. Can you believe it’s been 999 years since The Event? Someone should write a song about a festival ‘round this year. OMG, it’s been, like, two thousand and eight years! When it’s all written out on a wedding invitation or whatnot (i.e.g., in the year of our Lord, nineteen hundred and seventy six) the numericalishness really stands out. I get how we think of it now, and wouldn’t be surprised if it’s just one of those conventions that just is. But I thought there might be some explanation that was intentional (those busybodies at Trent thought commas looked like devil’s horns), typographic (Guttenberg’s press wouldn’t line up correctly after Tackleberry futzed with it), or some such practicality. Oh, about no comma in a four digit number. A few of my clients’ style manuals do that. They’re (the clients) international hodgepodges, if that sheds any light on it. Maybe it’s a Hodgepodgian thing? ---

The numerical character of years is also very evident if you write them in Roman numerals. where you have to do some math (adding to and subtracting from the nearest round number). [QUOTE=Rhythmdvl] Was it because the year is not an adjective? [/QUOTE] This is nitpicky, but I’d like to point out that ordinary numbers are not adjectives either, grammatically speaking. In a sentence like, “I saw four cars driving down the street,” the word “four” is not an adjective modifying the noun “cars,” the way (for example) “big” would be if I were talking about big cars. Number names are a category of words on their own. [Next page](https://boards.straightdope.com/t/why-don-t-we-put-a-comma-in-the-year-i-e-2008-not-2-008/452821.md?page=2)
