I use alarms on multiple devices to maintain a strict 7 days schedule.

For me, a 2:30am to 7:30pm local time wake schedule allows direct daily communication in all important time zones; it has the added advantages of allowing for decent morning rituals and a solid 4 hours before anyone local is online, and eliminating the typical activities most people engage in after 8pm..

Along the same lines, I start my personal weekly schedule on Friday mornings with the aim of preemption of Friday afternoon crises and preparation for whatever looks likely to come along the following Monday.

My experience is that any schedule allowing for less than 8 hours sleep time needs vigilant protection of the time one actually goes to bed to avoid sleep deficit.
