Your contributions, including commits, proposed pull requests, and opened issues, are displayed on your profile so people can easily see the work you've done.
Your GitHub Enterprise profile shows off your most popular repositories and repositories you've worked on recently as well as a graph of your repository contributions over the past year.
Your profile contributions graph is a record of contributions you've made to GitHub Enterprise repositories. Contributions are timestamped according to Coordinated Universal Time (UTC) rather than your local time zone. Contributions are only counted if they meet certain criteria. In some cases, we may need to rebuild your graph in order for contributions to appear.
