so there's 24 hours in a real-life day. There's 200 minutes in one year on half-speed in game time. I have been playing my VV1 tribe for 2067 real-life hours. How many Isola years has my tribe been around?

1/2 speed = 200 mins/yr
normal sp.= 100 mins/yr
2067 hours is equal to 124,020 mins
124,020 mins would be equal to 1,240 years n 2 months 13 days, assuming you started Jan 1, 0000. Year 1240 would be leap year.
So your date would be Mar 13 1240.

So basically my tribe was started 1,240 years ago? WOW.

Okay I could be wrong but I got roughly 620 years. Since there are 124,020 min in your game and you played at 1/2 speed, it would make 620 years. You didvide 24,020 by 200 (since you already know how many minutes it take sto get a year) to get the years.

I think its 1 hour / year.

1 real hour = 1 year for the villagers in 2x speed

On half speed it is 200 minutes. I was trying to find out how long my tribe has been going for in Isola years.

2067 hours x 60 min = 12402 min that you play
12402 min / 200 min = 620,10 years for your village
I think!

This doesn't really help you, but I just thought of something funny! You know that song with the line: "She'd've said 'yes' in a New York minute," ? Well look here at the change I made: "She'd've said 'yes' in an Isola minute," LOL!
