Mars Time: Clocks, Calendars, and a New Martian Standard

About this episode

Time on Mars isn’t just longer days. In this deep dive we explore how relativity and Mars’ orbital quirks affect local time, why a Martian day (the sol) runs 24h39m35s, and how the equation of time can swing by as much as 93 minutes over the Martian year. We then compare calendar schemes—the Darian model and the pragmatic Smoital system with occasional short days to keep solar noon stable—showing how a robust time standard could anchor navigation, life-support, and infrastructure for a growing Martian civilization.
