Martian Year

The Martian year is the time unit Mike uses to translate Earth chronology into a scale his own people understand. When he learns that the city he is viewing was founded a little over two Earth centuries earlier, he converts its age into Martian years: 3^4 + 3^3, or 108. The conversion makes human history countable in his terms without making Earth time feel familiar.

Meaning in Mike’s Frame of Reference

Earth’s units have no real flavor for Mike, so the calculation is more than a change of arithmetic. It places a human city’s age within a Martian numerical system and helps him understand its past on a scale he can use. The result does not erase the difference between the cultures’ experiences of time; it gives him a bridge across that difference.

The City’s Age and Mike’s Response

The calculation follows Mike’s questions to Jill and Dorcas and his effort to connect their answers with what he has read. Learning that the city is only a little over two Earth centuries old relieves his mind: by Martian measure, it is 108 years old. Yet the number does not diminish the city’s emotional weight for him. He regards it as young—an egg—and imagines returning centuries later, when he might be strong enough to grow close to its accumulated pain and beauty.
