The Hassan Martian Calendar (HMC): A Civil Calendar System Based on the Hassan's Martian Sol (HMS)
Version 2 expands the original HMS proposal into the Hassan Martian Calendar (HMC), a complete civil calendar architecture for Mars. It introduces a 668-sol standard year, a 671-sol leap year every fifth year, a sixteen-month structure, leap-sol distribution, and a design philosophy separating astronomical timekeeping from cultural conventions.
