The substitute Calendar offers a monthly view of your jobs (green), any leave you have entered (purple), and the days of the week that you have limited or no availability (yellow/red), all of which can be edited from this page.
To access your calendar, click Calendar at the top of the screen. You can navigate between months using the corresponding arrows.
To view more details on any specific job including any available notes and attachments, click the corresponding job to access the Job Details page.
For more information on adjusting your availability, see How to edit my weekly availability and How to enter full and partial day leave.
