Cassiopeia and Ursa Major (also known as the Big Dipper) are only visible all year long if you live in the northern hemisphere north of about 30 degrees North. For people south of that, it's only visible sometimes, and south of 30 degrees South, it isn't visible at all. Our Australian readers have never seen it, unless they've visited somewhere north of the equator.The reason is that Cassiopeia and Ursa Major are circum-polar at these latitudes; they never set, but they travel in big circles around Polaris, the North Star.
In the continental USA, you can generally see Cassiopeia in any season; it is circumpolar, meaning that it appears to revolve around the North Star. At latitudes below about 25N, it is generally visible only in the northern hemisphere's winter.
There are more than five stars in Cassiopeia but the major ones are as follows from the left of the 'W' / 'M': Caph, Beta Cassiopeia Shedar, Alpha Cassiopeia Cih, Gamma Cassiopeia Ruchbah, Delta Cassiopeia Sagin, Epsilon Cassiopeia
