Historical commits are attributed to my account but missing from contribution graph

Body

Hi,

I'm trying to understand why my historical commits are correctly attributed to my GitHub account but are not appearing in my contribution graph.

Context:

• My company's private repositories were previously hosted on GitLab and were later migrated to GitHub.
• The original Git history was preserved during the migration.
• My current GitHub account was created after some of these commits were originally made.
• About 2–3 weeks ago, I added and verified the email address that was used to author my historical GitLab commits.

I tested one historical commit from April 2025 and confirmed the following:

• The commit's author email exactly matches an email that is currently verified on my GitHub account.
• On the GitHub commit page, clicking the author links directly to my current GitHub profile.
• The repository is not a fork.
• The repository's default branch is master.
• I confirmed with git merge-base --is-ancestor that the historical commit is contained in origin/master.
• I am a member of the GitHub organization that owns the private repository.
• Private contributions are enabled on my profile.
• The commit's AuthorDate and CommitDate are identical.
• More than two weeks have passed since the historical author email was added and verified.

The commit itself is correctly attributed to my current GitHub account on GitHub, but it still does not appear in my contribution graph.

GitHub's documentation says that adding the email used for historical commits should trigger the contribution graph to rebuild, and that this may take up to 24 hours. In my case, it has already been approximately 2–3 weeks.

GitHub Support also suggested that this may require contribution attribution/recalculation, but my current support options are limited to self-service resources and Community Discussions.

Is there any additional condition for historical commits that were migrated from GitLab to GitHub?

Or is there a way to trigger a recalculation/rebuild of historical contribution attribution for my account?

Thanks!

From what I understand, the important distinction here is that commit attribution and contribution-graph indexing are not necessarily the same thing.

Since the historical commit is already correctly attributed to your current GitHub account, the verified email, author attribution, default branch, and repository-access checks appear to be satisfied.

There are also recent Community reports describing the same behavior: old commits become correctly attributed after an email is added/verified, but the contribution graph does not retroactively update even after several days. This suggests that the remaining issue may be GitHub's historical contribution indexing rather than the GitLab migration itself.

I don't know of a self-service way to force a contribution-graph rebuild. Given that you've already waited 2–3 weeks, I would recommend asking GitHub Support specifically for a manual contribution graph re-index/recalculation for the affected account/repositories.

The fact that the commit page already links the commit to your current profile is a good sign—the underlying attribution appears to be working; it's the contribution calendar that seems out of sync.

Thank you for the explanation.

I actually already contacted GitHub Support and requested a manual contribution graph re-index/recalculation.

However, my ticket was automatically closed with the following response:

"After reviewing your account and the nature of your request, the support resources currently available to you are GitHub Community Discussions, GitHub Docs, and GitHub Skills."

So unfortunately, my request did not reach a support engineer who could investigate or trigger a manual re-index.

Since:

• the historical commits are already attributed to my current profile,
• the author email is verified,
• the commits are on the default branch,
• and it has already been 2–3 weeks,

is there another way to request or escalate a manual contribution graph re-index?

Or is this something only GitHub Support staff can perform, meaning there is currently no self-service solution available to me?

Thank you!

Thanks for the clarification. Given that the commits are already attributed to your profile and you've already verified the email, default branch, repository visibility/access, and the 24-hour waiting period, I don't think there is another documented self-service method to force a historical contribution-graph rebuild.

There are also recent GitHub Community reports describing essentially the same situation: historical commits remain correctly attributed to the account, but the contribution graph doesn't get rebuilt after an email is added/re-added.

One important distinction is that commit attribution and contribution-graph display aren't necessarily the same thing. The fact that GitHub links the commit to your profile suggests the email association itself is working.

Since your Support request was automatically closed without reaching an agent, I'd recommend keeping this discussion focused on whether GitHub currently provides any supported escalation path for contribution-indexing issues when the normal Support route isn't available.

I wouldn't rewrite the company's Git history just to fix the graph, especially for a migrated repository with existing contributors. That would change commit SHAs and create unnecessary disruption.

If no escalation path exists, then unfortunately this may currently be a GitHub-side indexing issue with no user-accessible fix.

From the checks you've already done, the commit attribution itself appears to be working correctly. Since the commits are linked to your current profile but still don't appear in the contribution graph after 2–3 weeks, this doesn't look like the usual “add and verify the commit email, then wait up to 24 hours” case.

One additional thing I'd check is whether the commits are on the repository's default branch from GitHub's perspective and whether the repository is actually counting private contributions for your account.

If all of those conditions are already satisfied, I don't think there is a user-side command or API call that can manually force a contribution-graph rebuild. At that point, GitHub Support would likely need to investigate/recalculate the contribution data on their side.

Since the commit page already correctly attributes the commit to your profile, that strongly suggests the remaining issue is with contribution-graph processing rather than email attribution.
