It probably does, assuming consecutive days, without days off somewhere in the middle. We have a new roster pattern, normally 6 on and 3 off, but the 3rd day is known as a 'flexi day', which can be used not as a full flying day but to assist with late finishes and early starts, to help out with the programme. It does not then count as a day off.
Hope that helps, it is a very general description, rather than all the full complexities.
