What time of year can you see planets?
There are generally a couple of planets visible every night of the year. Which planets will be visible and when depends on where each of the planets (and the Earth itself) are in their orbits. Here on August 28, 2009, for example, Jupiter rises about sunset and is brightly visible all night. Venus and Mars rise before dawn. Saturn and Mercury are not visible this month, because they are too close to the Sun to be seen.

Are planets always visible?
The planets in our solar system are not always visible to an observer on Earth, for various reasons. Daylight reduces the visibility of planets significantly. Mercury and Venus, since they are inside the orbit of Earth (closer to the Sun), could only be seen in favorable conditions near sunset or sunrise and not in the middle of the night (or similar difficulties in solar transit, or other planets in opposition, close to the line of sight to the Sun). They would not be visible if occluded by a celestial body (or specifically if they are below the horizon). Neptune, being too distant, can't be resolved with the naked eye; exoplanets require sophisticated equipment to resolve.
