Easy Tech TutsHow To Show Subtasks on Calendar in Asana Easily 2026
By Impran M N
Subtasks in Asana don't show up on project or personal calendars by default, which can make your schedule look incomplete even when work is fully planned. This guide explains why that happens and walks through linking subtasks to a project and assigning due dates so they populate correctly on the calendar grid.
01Understand why subtasks are hidden
By default, subtasks don't automatically appear on project calendars unless they're explicitly connected to a project container.
02Open the subtask's details panel
Navigate to the subtask list under its parent task and open the details sidebar for the specific subtask.
03Link the subtask to a project
Use the project field menu to add the subtask to the same project workspace so it becomes eligible to appear on that project's calendar.
04Assign a due date
Set a clear due date on the subtask to trigger its calendar grid visual once it's linked to the project.
05Verify and customize the calendar view
Switch to the project's Calendar tab to confirm the subtask card appears, then adjust color codes and filters to manage clutter.
Frequently asked questions
Why don't my subtasks show up on the calendar even though they have due dates?
Subtasks need to be explicitly linked to a project, not just their parent task, before they'll populate on that project's calendar.
Will linking a subtask to a project change its parent task relationship?
No, a subtask can keep its parent task relationship while also being linked to a project so it appears on the calendar.
Can I show subtasks on my personal My Tasks calendar?
Yes, once a subtask has a due date and is properly assigned, it can appear on your personal My Tasks calendar view.
How do I avoid calendar clutter once subtasks start appearing?
Use calendar view filters and color codes to balance visibility between parent tasks and their subtask deadlines.
