Hanke and Henry would have twelve months with same names as those we use now. The year would have 364 days. The first two months of each quarter would have 30 days; the last, 31.The week would remain the same, with Sundays every seven days as a nod to the devout. However each date would share the same day of the week each and every year. Since Dec. 25 was on a Sunday this year, in their calendar it would always be on Sunday.
