Okay, so I currently have a CC that is 11 months ago (shows opened 7/1/2011), and my biling period closes on the 19th, so my balance is reported to the CRAs on the 20th (usually).  My question is, does having a card open for 11 months versus 1 year make a significant difference in FICO scoring?  I heard FICO rounds down, so my AAoA would actually show 0, instead of the .9 years, is this true?

I'm going to be applying for 2 new CCs (only have 1 at the moment, and it's my only line of credit), and I'm wondering if I should give it another month so it shows up as 1 year on all my reports before applying for anything.  Will waiting the extra month give my FICO scores a boost?

Here is where I currently sit:

EQ - one revolving account (never late, 11 mo. old), and 1 inquiry (6/5/11) Score: unknown

TU - one revolving account (never late, 11 mo. old), and 1 inquiry (6/28/11) Score: 698 (6/7/12 from myFICO.com)

EX - one revolving account (never late, 11 mo. old), and 1 inquiry (6/5/11) Score: unknown

Util is showing 8% for all 3 as well for my CC.

I suppose waiting an extra month would also make it so I wouldn't have any inquiries in the past year, which would probably also boost my score some.

Any insight or advice would be greatly appreciated.

Thanks!
