Here's the context.
There's a seminar about retirement planning and it will be held for two days.
Day 1 ends at 2 pm next Wednesday.
Day 2 ends at 3 pm next Thursday.
The seminars will end at a different time on each day.
Each day will end at a different time.
which one would you choose and why? Is there something else that you could recommend?
P.S. The reason we use 'A' right before 'different' is because we have only two days, not more than two days, right?
