Introduction to calendars

A calendar is a named record of dates that defines when working and non-working times take place. You assign calendars to tasks and resources within projects, to define the time during which they are available for working. For example, you could assign a calendar that defines the hours of daylight to a task that can only be carried out during daylight hours, and you could assign a calendar that defines the hours during which a plumber works to a Plumber permanent resource.

You can create as many calendars as you need in a project to reflect the working and non-working time of tasks and resources - each calendar can have different working and non-working periods. If you want to plan a project in precise detail, you might create a calendar for each individual resource; if you are happy planning to a less precise level of accuracy, you might create fewer calendars and assign each calendar to a group of resources.

You create and maintain calendars in Library Explorer. Two other Library Explorer objects are associated with calendars: work patterns and exceptions.
