the five day week

>

seven is an odd number. it also isn’t a great divisor. yet we choose it when dividing the days of a year into weeks?

five is also odd, but divides a bit more nicely into the year. quite a bit more nicely.

a modest division

shorten weeks to five days. and adjust the current twelve months to have thirty days each.

days can be called: onesday, twosday, threesday, foursday, fivesday.

each month then has six equal weeks. this neglects about five or six days which trail as a standalone “nil” week.

calendar

formatting the calendar is somewhat simple and included below for reference.

review basic comparisons to the traditional gregorian calendar also.

ramification of change

smooth social transition into new timekeepings is beyond the scope of this page.

i imagine there would be complications and some things might break.

instead the immediate benefits shall be touted and concerns quelled!

following the phases

luna, our wonderful moon, cycles through a full moon every 29.5 days.

clocking out

working a job monday through friday totals to 71.429% of week days.

this is close enough to 70% for practical purposes.

scheduling seven days of work across ten days brings opportunity for more asynchronous collaborations or perhaps more frequent days off without challenging existing arrangements around hours at a job.

workers routinely grinding from 9-5 regain just one hour over ten days.

multiplying moduli

constant multiples of five find familiar factors for the months and days.

calculating the day of the week and difference between days becomes elementary.

for example, jul. 24 is a foursday and happens 107 days before nov. 11.

modeling this calendar in code then commands plain arrays instead of specialized libraries. compatibility with the current notwithstanding.

coins in quarters

splitting a year into groups of four is customary and encouraged with an abundant number of weeks (72).

composing 72 might happen with 4 groups of 18, forming 90 day sets. trisections are also possible using 3 groups of 24, making sets of 120.

coincidentally 7200 minutes make up the 120 hours in a week.

the degree of effective days (360) matches the roundness of a circle.

observed ceremony

religious practices and cultural events often follow a weekly cadence.

changing the calendar would cause challenge and i cannot propose a solution. this is merely a thought experiment.

finding alternative measurements has been considered multiple times.

exploring every option is left as an exercise for the reader. below are a few brief reflections.

astronomical observations

the traditional chinese calendar signaled the solar signs and solstices!

lunisolar patterns predicated month lengths and every event followed.

natural sequences are valued but frequent adjustments to account for seasonal drifts are inconvenient.

perennial posits

the international fixed calendar set consistent days to dates each year!

equal months of 28 days standardizes weekdays. but with 13 months.

five day weeks achieve this anyways and without the unlucky number.

ten days a week

the egyptian civil calendar pioneered thirty day months long, long ago!

weeks were metered by ten days forming twelve months which about matched a five day scheme. though leap years were omitted.

roman reform added leap years but eventually gregorian was adopted. modern ethiopian calendars retain 30 day months albeit 7 day weeks.

truly original innovation shown ahead of its time.

the temporary french republican calendar placed ten days in the week!

revolutionary removal of royalty and religion requested a new calendar. decimalization was desired with ten appearing across times and dates.

similar balance between months was achieved with thirty day months and complementary days trailing.

a shifted start of the year and starting year makes this change drastic. longer hours in a day makes it unappealing.

ten months a year

the legendary calendar of romulus fixed ten months and ignored two!

months flipped between 30 and 31 days so a year was only 304 days long. winter months were left unorganized without farming tasks.

some accounts claim eight day weeks. organization feels forgotten.

the base ten numbering system is applied to everything in a deciyear!

ten months make a year and have 36 days each - 4 weeks of 9 days.

consistency in months is appreciated but the weeks become so long. subdividing a year begins to split months too.

millidays make time which simplifies calculations but changes much.

dated idea

tuesday isn’t real. time is only continuous and we build our constructs around it.

be in this moment.
