2027–2028 13 Month Calendar, International Fixed Calendar, Wooden Wall Decor

Explore an alternative way to view the year with a physical 13-month wall calendar for 2027–2028. Made from 3 mm plywood, this International Fixed Calendar display is designed for calendar enthusiasts, educational spaces, home offices, studies, and anyone drawn to unusual wall decor.

What is this?

This decorative wall calendar is based on the International Fixed Calendar concept, also associated with the Cotsworth Plan, Eastman Plan, or Yearal. Each year is arranged into 13 equal months of 28 days, followed by an additional Year Day outside the weekly cycle. It is an educational and decorative display, not an official replacement for the modern calendar.
