Calendar Details
The Calendar Details view in Fusion Online allows you to view and edit project, resource, user, and system calendars. Each calendar type shares the same functionality, with certain distinctions based on its specific role in scheduling tasks, resources, and assignments.

Calendar types
Project Calendars: Define task availability for scheduling. Tasks are scheduled based on the default project calendar, along with any resource calendars assigned to the task’s resources. Every project includes a default calendar.
Resource Calendars: Specific to each resource, defining their availability for tasks assigned to them. Resource calendars derive from a base project calendar, which you can select and override with custom working hours or exceptions.
System Calendars: Created by System Administrators, system calendars serve as the base calendar for new projects and can be used as base calendars for user calendars.
User Calendars: Define user availability, which the Assignment Scheduler uses when scheduling assignments. User calendars derive from a system calendar that can be customized with overrides to working hours and exceptions.
Key features
Name: For project and system calendars, you can change the calendar’s name in the Calendar Details view.

Base Calendar: For resource and user calendars, you can select the Base Calendar and adjust settings to override the base calendar as needed.

Monthly calendar view: Displays a summary of the current month’s working and non-working days, as well as any exception days. Use the arrows to navigate between months, and click on any day to view its detailed working hours.

Working Days and Days Off: Displays the count of working and non-working days for the selected month.

Editing options
Edit Weekly Schedule: Click this button to define the work week schedule in a dialog window.

Click the up/down arrow to the right of the day of the week to edit the working hours for the day.

Specify up to five work shifts for each working day.
For resource and user calendars, choose whether each day’s hours should follow the base calendar or be overridden with custom settings.

Add an Exception: Click + add an exception to open the exception dialog, where you can:
Name the exception and set a Start and Finish date.
Select if the exception is Nonworking or Working. For working exceptions, define up to five shifts for that period.

Fusion Online only supports creating consecutive day exceptions. Exceptions with recurrence patterns (e.g., weekly holidays) can be created in Microsoft Project with Fusion Desktop and are visible in Fusion Online, where they are fully honored by the scheduler. However, you cannot create or edit recurring exceptions directly in Fusion Online.
