I know I asked this before, but I don't think I ever got a response.


Is there a difference between "20's" and "20s" (in either ages or dates)?

Such as, "he was in his mid- to late-20's" versus "he was in his mid- to late-20s."

Or, "the 1990's saw a surge of economic growth" versus "the 1990s saw a surge of economic growth."


M'aidez! (Or as the Americans would say: "Mayday!")
