Garfield: Well, another year is almost under the belt.
Garfield: And I've had 668 pretty good days.
Garfield: We live on Mars.
The author writes:
By the way, that's 668 Martian days. If you were counting from Earth days, it'd be 686 days. (I'll conveniently ignore leap years, which are needed much more frequently on a Martian calendar, since the remainder for Mars' calendar is .5921, which necessitates more leap years then Earth's .2423.)
