Here are some tips on the best time to deliver training.
 The best time is first thing in the morning.
 As you approach coffee break interest wanes.
 As you approach lunch, audience attention is focused on the prospects of food.
 After lunch, audience attention is focused on digestion. Showing slides and films in a darkened room after lunch invites people to sleep. If your audience have been drinking, they can be inattentive, argumentative or sleepy.
 Training after dinner gives you the problems of subdued lighting, full stomachs, pre-dinner cocktails, and dinner wine.
 Speaking at lunch gives you the additional problem of people concerned with getting back to work.
 Dinner and lunch speakers should keep it short, keep it moving, and keep it interesting.
