Constellations are used for navigating. Since different constellations appear in different parts of the world at different times of the year, if you know the approximate time of the year you can figure out where you are by the constellations.
There are a total of 88 constellations. Which constellations you can see at any one moment depends on the time of the year, the time of the night, and your geographic lattitude.
It depends on your location and the time of year.

The circumpolar constellations
No. The pattern made by a group of stars doesn't change, although its place and orientationin the sky depend on the observer's location, the time of night, and the time of year.
This is due to Earth traveling around the Sun... it takes a year for this to happen. Which is why you see the same constellations in the sky the same time every year.
yeah the time of year but not time of day

Earth is revolving....
That Earth is orbiting the Sun.
During the year, due to the earth's orbit, different constellations appear during different seasons. You can use the constellations to determine the time of year.

Circumpolar constellations are visible all year long, depending on where you are viewing them from. At the north pole, or the south pole, some constellations are visible year-round, these are the circumpolar constellations. On the equator, there are no circumpolar constellations because of the earths rotation, that is why circumpolar constellations are at the "poles". Some of the circumpolar constellations can also be viewed from other parts of the same hemisphere, such as the big dipper and the little dipper, although they are circumpolar, they are also seen in other parts of the northern hemisphere. Circumpolar constellations in the northern hemisphere, will never be seen at the south pole, and vice versa. I hope this helped.
The observer's location and the time of the year :)
