The apparition period is the time that your planet is visible. It can last anywhere from a few weeks to almost two years. You can look these up in most astronomy catalogues to figure out when your planets are visible. Most of the planets are most visible as the sky gets dark (dusk) or as the sky begins to brighten again (dawn). However, looking for them in the night sky is also possible. You have to look very late at night, when it is incredibly dark out. Combine their apparition period with the time that they are most visible to determine when will be the best time to see the planet you’re looking for.  Mercury: this planet is visible multiple times a year. This year, it will still be visible in September and December. Mars: the early morning sky will showcase Mars. Starting in August, Mars will begin to climb higher into to sky and continue through the rest of the year. It will become brighter as it climbs.  Jupiter: pre-dawn skies are the best time to see Jupiter. It will appear in the 2015 sky in mid-September and continue for months inside the borders of Leo.  Saturn: look in the evening twilight sky for Saturn. Saturn will appear in the night sky in November and will be visible in the morning sky by the year’s end.
