Before you can view and manage your calendar, your user account will need to be linked to a corresponding Officer record in PICSWeb. If the links for Tasks, Calendar, Communications and Reports are not available from the side menu, this may be why.
To do this, a Database Administrator user will need to log in, go to Configuration > Users and Access > Users and Permissions from the side menu, find your user account in the list and select ... > Edit.
In the edit window, the administrator can search for the correct officer record to link to your user account. If a corresponding record does not exist, it will need to be created from the Officer list.
Once your account details have been saved, the next time you log in you will be able to access your calendar from the Workspace section of the side menu, along with your Tasks, Communications and Reports.
For more information, take a look at the full help pages for Calendar and Editing User Details.
