48 hour gold trial means over 2 days or 48 hours on Live?

I just got a 48 hour gold trial thingy and I just wanted to know before I activated it, does it mean 48 hours as in over a 2 day span IRL or 48 hours of playing on Live?

thanks

Obviously, 48 hours = 48 Days ...... on Pluto

48 hours on live is a really long time...the_leet_kid

haha right. was kinda happy at first til I thought about it..

oh wells. I'm gonna start gold again soon anyways, I'll be happy w/ free stuff
