The modern calendar (known as the “Gregorian Calendar”) is not set in stone. It was developed after centuries of scientific observation and trial and error. It’s still not perfect. Simpler and more uniform calendars—such as the “International Fixed Calendar”—have been proposed. Would it be a good idea to improve our calendar, and what would be the issues involved?
Should we reform the calendar?
Students will review our current calendar, including its pros and cons. They will also review alternative options, and decide if they are practical.
