Czuch Chuckers: That is what we are talking about.

The "Total game time". The example is 3/1/10 means:

3 days total game time for a person.
1 day added for each move
10 days is the MAX amount of time you can have.

So if it was 3/0/10

That would mean you would get no extra time, a person would have 3 days total to play the game (Meaning if both players use all their time, 6 days max until game is over) (Plus the /10 part would not matter since no time is added)

And there is no vacations or weekends used in these types of games.
