Do standups just before lunch. People tend to work on different schedules, start/finish early, start/finish late, but most tend to have their "middle of the day meal" at around the same time. So instead of 9 or 10am, or 4 or 5pm, do it at the "natural" break time, eg 12:00-12:15. Two advantages, people that have got "into" the work flow in the morning need to break anyway, people that use the morning for "admin" and then afternoon for work can finish their housekeeping with the standup. Same applies at the next order of magnitude, start/finish sprints in the middle of the week, not the beginning or end. No one wants to sit in a review on a Friday afternoon. Retrospectives make sense at the end of the working week. Planning makes sense at the beginning.
