International Fixed Calendar

The International Fixed Calendar is a proposed calendar system that divides the year into 13 equal months of 28 days each, plus an extra day (or two in leap years) to total 365 or 366 days. Each month has exactly four weeks, making scheduling consistent and predictable. This system aims to streamline planning, standardize weeks across the year, and eliminate irregular month lengths. It’s designed to improve efficiency, planning, and global coordination, though it is not widely adopted.
