Find the Create Date of GitHub Repo

You can use the API from GitHub to search it.

Like open the following link in the browser.
https://api.github.com/repos/{:owner}/{:repository}

Don’t forget to use your username and repository name to replace the {:owner} and {:repository}

Or, you are allowed to use the following command to show the create time more easily.

curl -s  https://api.github.com/repos/{:user}/{:repo} | grep created_at
