How to Check the Creation Date of a GitHub Repository?

  1. Copy Repo URL: Open the GitHub project page, copy the full URL from the browser address bar (e.g. https://github.com/vuejs/core) or the shorthand owner/repo.
  2. Paste into Search Box: Paste the link into the search box above. The tool supports all GitHub URL formats including branches, subpaths, and query parameters.
  3. Click Query: Click the "Find Creation Date" button. The system will automatically parse the owner and repo name and call the GitHub API.
  4. View Creation Date: The page immediately displays the exact creation date and time (automatically converted to your local time and UTC), along with the repository age in days.

Quick Query via URL Parameter (?q=)

This tool supports opening directly and auto-querying via the ?q= parameter in the URL, making it easy to share links in documentation, blogs, or chats:

  1. Full URL Support: For example, ?q=https://github.com/facebook/react, the system will parse the repository path and display the result immediately.
  2. Repository Shorthand: For example, ?q=vuejs/core, the page will auto-fill and query the creation date of the Vue repository.
  3. Share and Bookmark: After each successful query, the browser address bar automatically updates with the ?q= parameter for instant sharing.
