We propose a new calendar that preserves the Sabbath, with no exceptions. That calendar is simple, religiously unobjectionable, business-friendly and identical year-to-year. There are, just as in Eastman's calendar, 364 days in each year. But, every five or six years (specifically, in the years 2015, 2020, 2026, 2032, 2037, 2043, 2048, 2054, 2060, 2065, 2071, 2076, 2082, 2088, 2093, 2099, 2105, ..., which have been chosen mathematically to minimize the new calendar's drift with respect to the seasons), one extra full week (seven days, so that the Sabbath is unaffected) is inserted, at the end of the year. These extra seven days bring the calendar back into full synchrony with the seasons. In place of Eastman's 13 months of 28 days, we prefer 4 identical quarters, each having two months of 30 days and a third month of 31 days (see the accompanying permanent calendar**).
Moving on from the calendar to time, we recommend the abolition of all time zones, as well as of daylight savings time, and the adoption of atomic time — in particular, Greenwich Mean Time, or Universal Time, as it is called today. Like the adoption of a modern calendar, the embrace of Universal Time would be beneficial.
