THE SABBATH DAY IS AFTER 6 DAYS AND NIGHTS, WHICH IS TO TYPE THAT AFTER ANY 6 DAYS AND NIGHTS, THE 7TH DAY IS THE SABBATH DAY, MAKING THE SABBATH DAY USABLE WITH ANY CALENDAR. YOU COULD BE WITH MORE THAN ONE SABBATH DAY IF THE CALENDAR WAS 14 OR MORE THAN 14 DAYS AND NIGHTS, AND YOU COULD BE WITH LESS THAN ONE SABBATH DAY IF THE CALENDAR WAS LESS THAN 7 DAYS AND NIGHTS LONG.
