Hi @FazlayAhmad ...
Yes, the Canvas LMS (Learning Management System) is typically available every hour of the day. However, if you were ever to experience a situation where you couldn't log on to Canvas, one place to check is the status page:
Instructure Status
Now, if you are asking about courses you are taking, that all depends on the official start and end dates of those courses at your school, and it also depends on when your instructor publishes the courses. An instructor needs to publish a course to make the content available to students in the course. Typically, an instructor will publish a course maybe a few days ahead of the start date...or the actual start date of the course. You can still log in to Canvas prior to the course being published, but access to the course will be based on start dates and when the instructor publishes the course.
I hope I'm understanding your question correctly. If not, please provide some more details so that Community members might be able to help you. Thanks!
