Does Foreign work experience of less than a year in a company counts for 67 eligibility points.

HI. I am very confused about one thing. In the express entry profile, dates are entered month to month. But on employment letters, the exact dates are mentioned. So the hours will end up being different because of that right? Will my profile be declined? I am very worried.
What if my experience is more than two years but less than three years?
