How to Enable and Verify Trello Card Aging on a Board

Desired Outcome

Turn on Trello’s Card Aging feature so that cards that haven’t been updated for a configurable period gradually fade to gray. This visual cue helps teams spot stale items and decide whether to archive or act on them.

Prerequisites

• Access to the Trello board you want to configure (Board admin or Manager role).
• Web browser or the Trello mobile app (iOS/Android).
• Knowledge that the board is not using a template that disables the feature.

Procedure

1. Open the Board Settings
   • Web: Click the three‑dot menu in the top right of the board header.
   • Mobile: Tap the board’s name at the top, then tap the gear icon.
2. Navigate to Card Aging
   • In the menu, select Card aging (it appears as a sub‑item under Board settings).
3. Enable the Feature
   • Toggle the switch to On. A dialog will show the default threshold of 14 days.
   • Optionally adjust the threshold by entering a new number of days in the Inactivity threshold field.
   • Click Save to apply the change.
4. Confirm the Setting
   • After saving, the board header will display a small Card aging badge indicating the current threshold.

Expected Checks

• Visual Confirmation – Wait at least the configured threshold (e.g., 14 days) on a card that has not been updated. The card’s background should shift to a light gray, and the text will become less vibrant.
• Menu Verification – Re‑open the Card aging menu and ensure the threshold value matches what you set.
• Cross‑Device Consistency – Open the board on another device (web or mobile). The faded look should appear identically, confirming the setting is stored server‑side.

Recovery Options

• Disable Aging Immediately – If the feature interferes with workflow, toggle the switch back to Off in the same menu. Cards will return to normal color without data loss.
• Adjust Threshold – Reduce the inactivity days if cards fade too quickly, or increase them if the visual cue is not noticeable enough.
• Check Power‑Ups – Some third‑party add‑ons can override or hide the aging effect. Disable or reconfigure the relevant Power‑Up if the feature appears missing after enabling.

Limitations & Practical Checks

• Board templates created before the feature’s introduction may not expose the Card aging option. In that case, upgrade the template or copy the board to a new one.
• Board migration (export/import) does not carry over the aging setting. Re‑enable it on the destination board.
• There is no data loss when enabling or disabling the feature; only visual styling changes.
• To verify the effect without waiting, you can temporarily set the threshold to 1 day, observe the fade, and then reset it to the desired value.

Conclusion

Card Aging is a lightweight, visual tool that helps teams keep a pulse on board health. By following the steps above, you can enable it, verify its operation, and quickly revert if it clashes with your workflow.
