If you have a day job
, can you take more than seven days?
If you take more than seven days, is it still a seven day game?
When I've done seven day games while working a full-time job, I always took care to start on a Monday, so that during the work week I would use commute time to think about design, and maybe get a half hour of work done each night, and then worked all-out on the weekends to finish up. In general, I didn't even know what I was going to be doing until Thursday, anyhow, so I don't think that the full time job really slowed me down by much.
Although I'll grant that I didn't get many video games played or much television watched during those periods. But that's not necessarily a bad thing.
