Trello Created Date

Displays the creation date of each Trello card directly on the card. No configuration needed — install and reload Trello.

Trello Created Date is a lightweight Chrome extension that shows when each Trello card was created — directly on the card, below the other badges. Trello does not display card creation dates by default. You can find them buried in the card detail menu, but there's no way to see them at a glance across a board. Trello Created Date adds this information where you need it, using the card's own ID to calculate the date — with no API calls and no external requests. Features: • Shows creation date on every card, formatted in your browser's local language • Toggle visibility per board using the toolbar button • Also shows date and time in the card detail sidebar • Supports light and dark mode • Reacts in real time to board changes and new cards • No configuration needed — install and reload Trello • No data collection, no external requests, no permissions beyond trello.com and storage
