Every 76 years or so. The precise orbit is difficult to calculate precisely because the irregular thrust given off by escaping gasses, and by the variance of Halley's passes by the outer planets.
It's random when they appear, but they only appear on clear nights.

appeared
Characteristics that appear in recent parts of a lineage but not in its older members are often referred to as derived traits or innovations. These characteristics typically represent adaptations or changes that have occurred in response to a new environment or niche. They may include phenotypic traits, behavioral patterns, or genetic variations that have emerged more recently and are unique to the recent members of the lineage.

Edmund Halley was the fellow who first realized that the historical accounts of comets seemed to show that they were not solitary events; that they came back into view on a regular schedule. Examining the records, Halley calculated the probable orbit of the comet and concluded that the comet of 1682 was probably the same comet that had been seen in 1607 and before that in 1531. Halley predicted that the comet would once again be visible in 1758. When it was observed in December, 1758, it was dubbed "Halley's Comet", a title it retains.To astronomers, Halley's Comet is called "1P/Halley"; the 1P indicates that in the catalog of comets, this is the first entry and that it is "Periodic".

Halley's comet appears because it is a comet that orbits the Sun. It as a highly elliptical (oval) orbit which makes it seem to fly out of the solar system and back.
Because that's how long its orbit takes just like our orbit around the sun takes 12 months/ a year

No. It's a comet.
