On the 18 day schedule you will rarely go out less than 5 or 6 days. There is nothing set so it will be different each month. I have been scheduled to 17 days so far for the last two months and for next month also. This month I did an 8 day stretch and I'll start a 7 day soon. Then I'll have 4 off and work the last 2 days (and first 5 of next month). I have almost a 7 and 7 next month with all 7 day tours and a 6 day off stretch and a 7 day off stretch. It has worked out great for me so far. I haven't had a tour shorter than 5 days so far.
