Dear mouhamadyamin:

Five days
Used when you are simply talking about this number of days:
After five days of rain, we were ready for some sunshine.

Five days'
Used when you consider something as 'belonging' to the five days
In five days' time, the snow had nearly gone.

Five-day
Used when you consider 'five-day' as a single modifier:
We planned to attend the five-day seminar.

I hope this is helpful,

Petra
