Not too hot, not too cold.
No, not April 25. It's what @NASAExoplanets scientists call the habitable zone of a star—the range where liquid water could exist on a planet's surface: go.nasa.gov/41FqY3w

Have you heard of the habitable zone? You're in one right now. It's the distance from a star where you might find exoplanets with liquid surface water. We use the habitable zone to help focus our search for life beyond Earth.Exoplanet Exploration: Planets Beyond our Solar System

I'm sure there is still some water underground on Mars.
