Actually it is and it isn't. Thank you Compilation... Though its actually a bit of a typo on the wiki. The games timeline starts in 1959 (ignoring the rough 2000 year before era when Jenova arrived) of the VII calendar and after 1999, the calendar inexplicably goes to the date of 0000 for reasons unknown despite being mathematically improbable since Zack left to join SOLDIER in 1995 of the timeline.

According to VI's timeline, the game starts in the year 0 of their Calendar. with the timeline descending from the War of the Magi in the year 1000, so I'm not surprised Squenix would use an amusing number scheme and calendar system like our own. I'm surprised it didn't take place in the year 777 to be honest.

So, according to the 10th Anniversary Ultimania Omega Compilation (lord that's a mouth full) the Official Timeline of the Compilation of VII has the story starting 12/9/0007 in the VII universe. The game ends late in January of 0008. So the time is off but the information is only sort of incorrect by one digit.

The FF Wiki is usually pretty good about faq checking their resources. Its only when you read about upcoming titles or materials only released in Japan that things get fishy. The community usually puts a lot of effort into keeping everything accurate.
