I’m looking to find the creation date of different GitHub repositories, but I’m facing some challenges with the traditional method.
Right now, I’m trying to locate the very first commit to understand when the repository began, but this process becomes extremely tedious when dealing with projects that have hundreds or even thousands of commits. It’s not practical to scroll through all those pages for commits when I’m trying to get this information.
Is there a faster way to obtain the creation date of a repository? Perhaps there’s an API I can use or another strategy that could help me avoid sifting through all the commit history?
Here’s another time-saver I’ve been using: GitHub CLI with a one-liner for checking multiple repos from the same org. Just run gh search repos --owner=organization-name --json name,createdAt and you’ll get creation dates for all their public repos at once. Way better than hitting the API individually when you’re doing bulk research. The JSON output is clean - you can pipe it to other tools or just eyeball it. Perfect for competitive analysis or mapping out an organization’s development timeline.
You need to efficiently obtain the creation dates for multiple GitHub repositories, and manually checking each repository’s commit history or webpage is impractical, especially when dealing with a large number of repositories.
Step-by-Step Guide:
Automate with Latenode (Recommended): The most efficient solution is to automate the process using a workflow automation tool like Latenode. Latenode allows you to create a workflow that iterates through a list of repository URLs, retrieves the creation date from the GitHub API for each repository, and outputs the results in a clean report. This eliminates the need for manual checks and significantly reduces the time required for this task. This approach is particularly beneficial when dealing with numerous repositories or when this process needs to be repeated regularly.
Using the GitHub API Directly (Alternative): If you prefer a code-based solution, you can directly access the GitHub API. For public repositories, no authentication is needed. Here’s how you can retrieve the creation date:
a. Retrieve Repository Information: For each repository, make a GET request to the GitHub API endpoint: https://api.github.com/repos/{owner}/{repo-name}. Replace {owner} with the repository owner’s username and {repo-name} with the repository name.
b. Extract created_at: The API response will be a JSON object containing various repository metadata. The created_at field provides the repository’s creation timestamp in ISO 8601 format (e.g., 2024-10-27T14:30:00Z). Parse this timestamp to obtain the creation date in your preferred format.
c. Iterate and Store: Repeat steps (a) and (b) for each repository you’re interested in. Store the creation dates in a data structure (e.g., a list or dictionary) for easy management and later analysis. You can use any programming language (Python, JavaScript, etc.) and its respective HTTP request libraries to accomplish this.
Using the gh CLI (Command-Line Alternative): The GitHub CLI (gh) provides a convenient way to interact with the GitHub API from your terminal. You can use the following command to get the creation date of a repository:
gh repo view owner/repo-name --json createdAt
This command requires the gh CLI to be installed and configured. Similar to the direct API method, you’ll need to loop through your list of repositories and execute this command for each one.
Common Pitfalls & What to Check Next:
Rate Limiting: The GitHub API has rate limits. If you’re making many requests, you might encounter rate limit errors. Implement proper error handling and consider using techniques like exponential backoff to manage this.
API Authentication: While not needed for public repos, authentication with a Personal Access Token (PAT) might be required for private repositories. Consult GitHub’s API documentation for details on authentication.
Data Handling: For large numbers of repositories, consider using efficient data structures and handling potential errors (like repositories not found) gracefully.
Error Handling: Always include robust error handling in your scripts. This includes catching exceptions, handling rate limits, and providing informative error messages.

just use browser dev tools - no need to mess with apis. right-click the repo page, hit inspect, then search for “created” in the html. github embeds the creation timestamp in the page metadata, so you’ll find it quick without any coding.
You can find the creation date of a GitHub repository directly on its main page. Look for the sidebar; it typically displays the creation date below the repository description under the stats section. This method is quick and eliminates the need for API calls or command line tools, making it efficient for checking multiple repositories. Additionally, visiting the /pulse page of the repository provides an overview of activities, including when it started.
The GitHub REST API works great for this. Just hit https://api.github.com/repos/owner/repository-name and you’ll get the repo metadata with a created_at field that shows exactly when it was created. I’ve done this tons of times for project research. It’s instant and doesn’t need auth for public repos, way better than digging through commit history. If you’re more of a command line person, you can also use gh repo view owner/repo-name --json createdAt.
Standard methods often miss key details with archived or transferred repos. I’ve seen cases where the visible creation date is way off from when the project actually started - usually because it got moved between organizations or users. For accurate tracking, I use the API method plus check the earliest commit timestamp with git log --reverse --format="%ai" | head -1 after cloning locally. You get both the repo creation metadata and the actual first commit, which can be totally different in transferred repos. This dual approach has saved me from making wrong timeline assumptions during due diligence.
