Related PRs:

No related PRs — frontend only change.

Main changes explained:

• Updated src/components/TeamMemberTasks/TeamMemberTask.jsx to display a task age badge below the progress bar, calculated from task.createdDatetime
• Updated src/components/TeamMemberTasks/style.module.css to add styles for the task age badge with color coding (green ≤7 days, teal ≤30 days, yellow ≤90 days, red 90+ days)

How to test:

1. Check out branch Sayali-Task-Age-Indicator
2. npm install && npm run start:local
3. Clear cache, log in as admin
4. Navigate to Dashboard → Tasks tab
5. Verify a colored badge showing "XX Days Old" appears below the progress bar for each task
6. Verify color changes based on age (green=new, teal=recent, yellow=old, red=very old)
7. Verify dark mode works correctly

Screenshots:

Note:

Frontend only change. task.createdDatetime is already included in the API response from getTasksForTeams in taskHelper.js — no backend changes required.

Hi,

I tested this locally. The "XX Days Old" badge appears correctly below the progress bar for each task. Color coding works as expected, green for new tasks, teal for recent, yellow for old, and red for very old. Dark mode looks good too.
