So if you just combine two five-week rotations but have all the Day on-shift weeks in the first half and all the Night on-shift weeks in the second half (like Training-Days-Days-Days-Days-Training-Nights-Nights-Nights-Nights), you effectively get six weeks of 'days' - as Training is a day-schedule week - followed by four weeks on nights.
This only works if you work one of the schedules where the Day and Night periods are the same number of days, and arranged roughly the same way, so you can more easily swap them around. If you work a hybrid schedule it's different.
