Once I said 'It was the first year when the tour program began'
but after saying that, a question has arisen in my mind.
Because they are still offering people that program in a certain period of every year.
So, I think I should have used 'has begun', like 'It was the first year when the tour program has begun?'
Which expression is better for this situation?
Is the verb 'begin' suitable for the word 'tour program'?
and I am wondering if all these texts are understandable, or not.
Thank you very much.
