Using Hanke-Henry Calendar and World Calendar with Leap Weeks simultaneously

Dear Calendar List:

One criticism of the Hanke-Hnery Calendar is that the months with 31 days are at the end of each quarter, whereas some would prefer the months with 31 days to be at the beginning of each quarter, as in the World Calendar, used with or without leap weeks.  Yet, given that each quarter of the World Calendar begins on Sundays, whereas the current version of the HH Calendar begins each quarter on Mondays, they can both be used simultaneously as leap week calendars with a little trick of nomenclature.

The first days of each quarter of the World Calendar (with a leap week rule same as HH, and ISO 8601), can be Sundays, 0 January, 0 April, 0 July, and 0 October, which would correspond to Sunday, 31 December, 31 March, 31 June, and 31 September in the HH Calendar.  Both calendars would be the same, except for the 4 overlapping Sundays.  And, this would be the least disruptive to workday schedules, as most people have Sunday either as a day off, or part of a weekend.

Another way, slightly more complex, but useful without completely modifying the current Gregorian Calendar, is to use my alternative month names for the current version of the HH Calendar (with Monday quarter starts), with 0 Janum, 0 Aprilum, 0 Julum, and 0 Octum, in place of 31 Decum, 31 Marchum, 31 Junum, and 31 Septum, which are described here in the Calendar Wikia:

Dear Walter and Calendar People


Monday 1 has the disadvantage of occurring within a month.

Dear Karl

My arrangement would allow the user to choose which day to start the year or quarter, either Sunday 0, or Monday 1.

In terms of work schedules, either choice makes no difference. There would be 13 weeks of 5 Mon-Fri work days, for a total of 65 work days, excepting holidays, in any ordinary quarter.

One could run my Week and Month calendar alongside the HH calendar and each month would begin on the nearest Monday to the first day of the corresponding HH month.


I remember working out that 30 30 31 is optimised for ensuring the HH months begin as close as possible (within the calendar design constraints) to the corresponding Gregorian months, but not for the Sunday starting weeks of the original design.


Walter's suggestion makes the years start one day earlier and so not as close as possible to the Gregorian new year.

If instead, the years began on the nearest Sunday to the Gregorian New Year's day that resulting leap year cycle would be symmetrical like in the Gregorian calendar, but the close correspondence to HH would be lost in some years.


My opinion about HH and similar remains that having months of 31 and 30 days is pointless in a leap week calendar, because one would require either a leap week month of 7 days or a month of 38 or 37 days containing the leap week.
