That's the internal way I measure things. The game doesn't skip one week, it skips 7 days in the game engine. For the player, everything in game is measured in weeks so you don't have to worry about days at all. Just divide the numbers I gave you by 7 and round up.
It gives me more flexibility and option in the future. The intro I'm working on is a good example.
The game starts, you meet Billy and you spend the night at his house. This passes time by one day. I have few planned features that will also require moving time in lower increments than one week, or even higher increments. It even supports time passing in smaller increments, like hours or minutes. This is used for minor activities like mining or working out.
