No it has not. The UK date system is DD/MM/YEAR, so it is valid for 30 days.

Thanks man sorry about that I feel so foolish and yes I am american.

I received my tier 4 visa but the visa vignette says "valid from 09/09/2017 to 09/10/2017" (MM/DD/YEAR). My specific travel date was the 16th, im not sure if they made a mistake while issuing it but isn't the visa supposed to be valid for 30 days?
