Gaining significant FICO points for account aging requries years of aging. Usuall five or more years.
Wow, if this is indeed true this is very sad news because it would then take years and years for my FICO to recover from adding new account. I'll never reach 700s then because I only have 3 small credit cards which is obviously not enough so I wanted to slowly keep adding tradelines...sigh 
Well, there is some evidence that there's a ding for "new credit" which goes away at 6 months (as long as you don't have any accounts even younger.)
I'll let you know in another month! 
I just read that it might only count until after it's been "reported" for six consecutive months (green squares) so I'm keeping my fingers crossed!

I thought it was one year, too, but the last time I got a new account, the flag vanished at six months. I don't know how authoritative those flags are, but the score increase cheered me up.
One year, two years, etc. mark it getting another year older. That sounds well duh, I know, but I think the birthdays help. Also, at one year, the associated inq is no longer scored, so there might be something there as well.
My only newish account will hit six months in October, so I will attempt to remember 
that we've been wondering about this, and see what if anything changes on my scores.
I just had an account hit the 6 month mark(EQ States Months Reviewed - 6) and didn't get a single point.

Did you have a new account negative on screen 2 before this? Did it go away?
