Can you adjunct ONLY during evenings + weekends?

Hello. Although I have a full-time job, I am interested in being an Adjunct [mostly for fun and a little vacation money]. Is it possible to ONLY adjunct during the evenings and weekends? The website for my local community college states that adjuncts must be available to teach days, evenings, and Saturdays. Is it possible to request only evenings and Saturdays? If I am offered a day class, can I turn it down without destroying my future opportunities? Thank you.
