While you might have some general working hours in your organization, some resources may not stick to those hours. You might have one person working a night shift, or someone else working four ten-hour days. Or, you might have a piece of equipment that runs nonstop. In Project, you can set a unique schedule for a specific resource.

What else can I do with calendars?

Project enables you to fine-tune scheduling using multiple calendars. If you understand how they all work together, it's easier to plan for how your project's dates will be impacted. Here are a few more articles you might find helpful in building a more accurate picture of the working and nonworking days in your organization.
