Check out The Chart. Look carefully at the chart above. The alternating periods of light and dark caused by the earth's rotation are represented by the light and dark bands. Thursday's work period occurs in darkness, but sets you up for a sun-drenched weekend. Your 40-hours of work start at the same time on both the 24 and 28 hour day graphs, but on the 28 hour day graph, your work for the week is over sooner, leaving you with a longer weekend.
Every day is different.
Since waking and sleeping is not synchronized to light and dark, each day of the week has its own unique character. This will aid your memory in distinguishing one day from another. Sleeping late on the weekends doesn't cause you to miss daylight. Friday, Saturday and Sunday are offset in a way that gives you maximum daytime in your free hours. Wake up Friday just as the sun is setting.
