Multiple Calendars

Hello, all.  I am a Project Manager in charge of new manufacturing product launches.  I'm looking for a project management software with better collaboration capability than what my company currently has.  Wrike looks like it may have what we need.  I don't think I'll be able to learn how to use this system well enough in just a 2 week trial though.

Right now, I would like to know how to use multiple calendars in a single project.  For example, how can I apply a weekday only schedule to planning tasks and a weekend schedule for equipment modification jobs?  How do I edit the timescale to change the standard 8 hour day to 12 hours or 24 hours?
