please I need at least one source for each question

these are the questions I wanted to be answered 

and I did attach a word document that talks about our company so you would have an idea about it.

1. What holidays, religious celebrations or other events should you be aware of that might impact the schedules of those from your assigned country? What is the time difference in this country and how might that impact scheduling as you do business with this company?

2. Should you take gifts with you when you visit this country for business dealings? If so what would be appropriate to take?
