Yes, the time it takes for a comet to complete 1 orbit is called a period.
It is called an orbit. A comet has an eccentric or parabolic orbit.
An orbit
33 years.
The orbital period of Halley's Comet is about 75.3 years.
Any comet visible from earth is in orbit around the sun. If the orbit is closed (elliptical), the comet will return after some period of time. If the orbit is open (parabolic or hyperbolic), the comet will escape the solar system and never return to the neighborhood.

33 years.
A comet that's bound to the sun and appears periodically is in an elliptical orbit. A comet that whizzes through the solar system only once and then leaves for good is in a hyperbolic orbit. If the comet is periodic but with an exceptionally long period ... thousands of years e.g. ... then we can't tell, from the small part of its orbit that we can see, whether it's elliptical or hyperbolic.
The shape of a comet's orbit is called an ellipse. This shape is a sort of narrowed circle and comets move in this shape around the sun.
Long-period comet
A comets orbit is considered a cycle because a comet circles back in an elliptical orbit.
