Kara no Kyoukai's timeline is supposed to be April, 1994, but then ufotable moved it up to 1995 to avoid anyone being minor.
Mirai Nikki's LN timeline of Merca's adventures with Shiki's daughter Mana is supposed to take place in the year 2008, but ufotable moved it 2 years, making it 2010.
And going by Fate's new timeline, what is supposed to be 2004 in VN timeline is ufotable saying "yeah, let's move it at notches up".
