I've got my own theory about the name 358/2 days.
We've already played 7 of the 365 days that Sora was put to sleep in Castle Oblivion, the 7 days of the tutorial at the beginning of KH2. Anyone remember that? He was asleep for a whole year. So 365 minus 7 is 358. The /2 could possibly mean several things. One, representing Sora divided by two, into Sora and Roxas. Or, one year divided by two, 1/2, representing a halfway point between CoM and KHII.
Or, I read somewhere that it represents the year of Roxas being alive and the 2 days Sora spent in Castle Oblivion before being put to sleep as Namine picked apart his memories. This doesn't make as much sense to me though.
