Accessing and Understanding the Project Calendar

The first step is to understand where to find and how to navigate the project calendar. The project calendar is where you define working days, hours, and exceptions for your project.

To access the project calendar, click on 'File' in the ribbon, then select 'Options'. In the 'Project Options' dialog box, click on 'Advanced', and you'll find the 'Calendar' section at the bottom. Click on 'Calendar...' to open the 'Change Working Time' dialog box, where you can modify your calendar settings.

Defining Working Days and Hours

In the 'Change Working Time' dialog box, you'll see a grid representing the days of the week. Clicking on a cell will toggle that day's work status between working and non-working. To set working hours, click on the 'Work' cell for the desired day, and enter the start and end times for your workday in the 'From' and 'To' fields.

For example, if your team works from 9 AM to 5 PM, Monday through Friday, you would set the 'From' time as 09:00 and the 'To' time as 17:00 for those days. You can also set a default work time for all days by clicking on the 'Set default work time' checkbox and entering the desired hours.

Setting Exceptions and Holidays

Sometimes, you might need to account for exceptions, such as holidays or specific project milestones that fall on non-working days. In the 'Change Working Time' dialog box, click on 'Exceptions...' to open the 'Exceptions' dialog box. Here, you can add holidays, set project-specific working days, or create custom exceptions.

To add a holiday, click on 'Add', select the holiday type (e.g., 'Floating Holiday'), enter the holiday name and date, and click 'OK'. To set project-specific working days, select 'Project-specific working days' and enter the start and end dates for your project. You can also create custom exceptions by selecting 'Custom' and defining the exception's name, date, and working hours.

To create a new calendar, click on 'File' > 'Options' > 'Advanced' > 'Calendar', and then click on 'Copy' or 'New' in the 'Change Working Time' dialog box.

To apply a calendar to your project, click on 'Project' in the ribbon, then select 'Properties'. In the 'Project Information' dialog box, click on 'Change Calendar', and choose the desired calendar from the list. You can also apply a calendar to individual resources or tasks by right-clicking on the resource or task and selecting 'Change Calendar' from the context menu.
