No, Todoist doesn’t support start dates that hide your tasks until their start date is due. This would prevent you from easily accessing important task information like comments. By keeping your tasks visible in your projects, you are able to access and manage all their details at any given time.
Despite Todoist not supporting actual start dates, it does support a start-date-like workflow which allows you to focus on the tasks you’re actively working on:
When you don’t want to see all your tasks at once, use the Today view or create a custom filtered view. This way you can focus on the tasks that you actively need to work on right now.
