Deductions & credits

I think my original message got chopped off. Actually, it's just the reverse... I need to know, by IRS reckoning, how many days I was in the USA

QUESTIONS: Using the IRS method of counting days (above),
- How many "full days" was I present in the USA?
- How many days was I in the USA on business?

August 7: Drove from Canada and entered the USA at 2pm.
August 7th & 8th: Spent personal time at grandparents' house.
August 9th:  9am, departed by car for another state for business.
August 9th - 13th Spent time on business.  On the 13th at 5pm drove to grandparents' home (again in a different state).
August 14th: Spent personal time with grandparents; left USA and re-entered Canada around 5pm.

 

Thanks!
