10
Numbered months
The year is divided into 10 self-contained metric months, alternating between 36 and 37 days.
A public-interest calendar framework
A better rhythm for the year.
Metric Calendar is a practical 10-month calendar framework built around focused work, predictable rest, and balanced planning.
6
Day metric weeks
Each metric week contains four Focus/Work Days followed by two Rest Days.
5
Bonus Rest Days
Every even-numbered metric month has one additional Bonus Rest Day outside the metric week cycle.
The model at a glance
Metric Calendar keeps the civil year aligned with January 1 while redesigning the internal rhythm of months and weeks.
How it works
Each metric month begins with Day 1 and contains six complete metric weeks. The 37th day of every even-numbered month is a Bonus Rest Day, outside the regular metric week cycle.

The technical term “Work Day” may be used in the specification. Public-facing copy uses “Focus Day” first.
Designed around productivity without burnout.
Metric Calendar is not just a tidier date system. Its central proposition is that the year can be structured around focused effort, predictable recovery, and clearer planning cycles.
