Region, Manufacturer, and Date range definitions

The people at Turn 10 do not understand how centuries work.

I decided I’d work on some challenges and do Old Timers, which is to complete 10 races in any car from the 20th century.

I chose the 2000 BMW 323ti Coupe and did a few races. After 3 races I realize it wasn’t counting towards the challenge. I chose another car from the 90’s and of course the challenge progressed just fine. It dawned on me the people at T10 coded the game incorrectly with the assumption that centuries start on the nnn0 year and end on the nnn9 year.

The 1st century was the year 1 A.D. to the year 100. 2nd century was 101 to 200. So on and so on.

The 20th century is the year 1901 to 2000, not 1900 to 1999. This is because there is no such thing as year 0 A.D.

I can’t believe I’m having to explain this on a game forum to a triple-A game developer/publisher.

Maybe this is nit-picky, but that doesn’t make it any less wrong.

There are a couple ways to think about this, both importantly focused on how the game works within its own system and not as defined by outside conventions:

  1. If we agree that a century is ten decades, and the 20th century is the 1900s, there are 10 decades starting with the 1900s, 1910s… through the 1990s. I would think most people would agree that the year 2000 is not in the 1990s.
  2. Think of how you might code this in the software to search for eligibility. By searching for the first two digits of “19” you’d also exclude the year 2000.

Yes, most people would agree that the year 2000 is not in the 1990s. But it is in the 20th century. @Strayborne is 100% correct. the 20th century goes from January 1, 1901 - December 31, 2000. No debate. If in doubt, please google it. The correct answer will be given.

The coding you suggested would not be the correct coding. Any programmer worth his/her salt could easily code this correctly.

If your system is not going to use proper conventions, then your rules need to be spelled out completely. A better description might be “Cars built before the year 2000”.

As a former math teacher I will tell you it is difficult enough to teach our students the correct facts without software companies reinforcing incorrect information.

None of what you said changes the fact that a year 2000 car is a 20th century car. The challenge clearly states, “Complete 10 races in any car from the 20th century.”

Determing the century from a year is a solved problem. I don’t understand why this is so difficult…

There’s also “Drive your car the way it’s meant to be dirven“ on the Drivers Club sign at Lime Rock. Doubt that will ever get fixed, but I accept it doesn’t impact the game.

Yep, it’s still there (as of Aug. 14, 2025).

There was also the time you could race the Chevrolet Beretta in the BMW only races.

So, if it’s possible for a “BMW” filter to include one Chevrolet on accident, surely it’s not that much harder for a “19XX” filter to include “2000” on purpose.

While it’s technically correct that a car from 2000 is car from the 20th century most people won’t see that as how it works. They’ll just see 2xxx and stop there and assume 21st.

Then there’s other non-gregorian calendars…

20th century does not include year 2000. It has nothing to do with decades.

For the filter, it’s not that difficult to search for years after 1900 and before 2001 exclusively for 20th century.

Wait, what? I feel like you’re saying two different things here. First, you say that the year 2000 is not part of the 20th century (it is).

Then you offer a suggestion for how to yield search results that would include cars from the year 2000. :face_with_spiral_eyes::thinking:

Sorry I missed my point! :sweat_smile: (I don’t know how I could have said the opposite above)

2000 is obviously in the 20th century, the 21th started with year 2001.

Thanks for correcting my mistake!
