There was an episode titled "The Other 48 Days", so 39 is definitely wrong. Day 48 is when the two groups merged. My guess would be that they've been there about 50-52 days.4inziksych said:I saw a commercial that said they were on (I think it was day 39) on the island. I know the show is in its 2nd year - is it hard to remember that it's only been that long or do you sometimes think it's longer. Do they have characters say things that remind you?
