A repeatable month
Each month has 36 regular days. Even-numbered months have a 37th day; month 10 has a 38th in leap years.
A calendar proposal
What if the year had ten months, and every metric week made room for four days of focus and two days of rest?
Metric Calendar rearranges the familiar 365 or 366 days into a repeating structure. The year still begins on January 1. The way we divide it changes.
6 weeks · 36 regular days
| Focus1 | Focus2 | Focus3 | Focus4 | Rest1 | Rest2 |
|---|---|---|---|---|---|
| 01 | 02 | 03 | 04 | 05 | 06 |
| 07 | 08 | 09 | 10 | 11 | 12 |
| 13 | 14 | 15 | 16 | 17 | 18 |
| 19 | 20 | 21 | 22 | 23 | 24 |
| 25 | 26 | 27 | 28 | 29 | 30 |
| 31 | 32 | 33 | 34 | 35 | 36 |
The idea in a minute
The length of the day stays the same. So do the year number, January 1 alignment, and leap-year rule. Here is the proposed structure.
Each month has 36 regular days. Even-numbered months have a 37th day; month 10 has a 38th in leap years.
Four Focus Days followed by two Rest Days, repeated six times per month. These labels describe the proposed rhythm.
A Bonus Rest Day closes months 02, 04, 06, 08, and 10, outside the regular metric week. No day disappears.
See the whole year
Five pairs of months: 36 + 37 days.
5 × 73 = 365 days, plus one in a leap year.
Why explore it?
Regular month layouts make the calendar easier to describe. Whether that makes life easier is a question for people, organisations, and research.
Every month begins with Focus Day 1. The six regular metric weeks have the same layout.
Keep Gregorian dates alongside Metric dates to explore a different view of your year.
A six-day cycle shifts against the seven-day week. Family schedules, observances, and services need deliberate attention.
A proposal, with open questions
Studies of shorter working time provide useful context. They do not test this calendar’s ten months or its six-day metric week, and they do not guarantee productivity or well-being gains.
