> Avoid Wednesday and Thursday afternoons. These are the most popular times to offer, meaning the potential for conflicts is high.
In case anyone else was interested in just their answer to the title question.
I always curse people who schedule meetings first thing in the workday, last thing in the workday, or immediately adjacent to lunch time. If the meeting is an hour long, I'll avoid attending an 11am meeting if I possible can.
Meetings that are adjacent to lunch are fair game. They just need to start/end on time.
Well, it can work, of course. I often have meetings scheduled like that. I hate it, though, because it means that I either have to cut lunch short or skip it altogether. A meeting may start and end at a set time, but I'll still need 10-15 minutes before the meeting to prepare, and sometimes 10-15 minutes after the meeting to perform action items that can't wait (such as updating my task list, my work notes, etc.)
(Lest people think that I value lunch too much, in nearly every place I've worked, taking lunch was required by management. If it weren't, I'd always skip lunch so that I could have an 8 hour long instead workday of 9)
The Wednesday one rings true. I always have an absurd number of conflicts on Wednesday.
