Quick Summary

The International Fixed Calendar is a proposed perpetual calendar reform. It divides the year into 13 months, each with 28 days, plus an additional day at the end of the year. This structure ensures that each month begins on a Sunday and ends on a Saturday, creating a consistent weekly cycle. A new month, named Sol, would be inserted between June and July. In leap years, an extra day would be added after June 28. This calendar aims for greater regularity than the current Gregorian system, though it has been criticized for not dividing easily into business quarters.1
