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:
Start tasks and sub-tasks
If you want to start a project on a specific date, add a "start [project name]" task in the project and set the due date for the start day. Then drag and drop the project underneath a parent project like "Someday/Maybe" to hide it from your task list. When it comes time, your start task will appear in your Today view to remind you to get started.
Similarly, if you have a date where you want to start a particular task, add a "start task" sub-task and set the due date for the day you want to start that task. When it comes time, that sub-task will only show up in your Today view as a reminder to get started.
Recurring due dates
In place of a start date, you can have a task that recurs for every date you want to be working on this particular task.
Set a recurring due date with both a start and end date. For example, type "every day starting may 3 and ending may 6". The task will appear in your Today view on May 3. Each time you complete the task, it will reset for May 4, May 5, and May 6.
You can also set an open-ended recurring due date like "every day starting may 3". When you've finished the task, select "Complete forever" from the task options menu to complete and remove it from your active task lists.
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.
