Body

I created a GitHub account for work, which I have finished now and want to merge with my personal GitHub account. All the calendar commit histories are associated with my work email address, which has now been deactivated. Is there any way to just duplicate my contribution calendar to my personal account? I DON'T need the contribution specifics/repositories to be copied over, just the calendar of contribution history. (Can I just add the work email to my personal account and leave it unverified?)

Hey, you can't directly transfer or copy the contribution calendar from one GitHub account to another.

But if those commits were made using your work email, there may be an easier solution add that email address to your personal GitHub account and verify it. GitHub can then associate commits authored with that email with your personal account, as long as the commits otherwise meet GitHub's contribution requirements.

So before trying to move repositories or rewrite commit history, I'd first try adding the old work email under Settings -> Emails on your personal account.

GitHub doesn't provide a button to simply merge one account's contribution history into another.
If you still have access to the work account/email, I'd definitely try the email approach before doing anything else.

The thing is I lost access to the work email already because my work period is over so won’t be able to verify a new link sent to it. If the email is unverified would it still work? I forgot to migrate it before work termination.

Ah yeah, if you no longer have access to the work email, that makes it a lot harder. GitHub normally requires you to verify an email before properly adding it to your account, so just adding the old address and leaving it unverified probably won’t bring those contributions over.
The commits themselves are still tied to that old email address.

If recovering access to the old email isn’t possible, I think contacting GitHub Support and asking whether they can help with attribution is probably the safest next step.
And for future work accounts, definitely add your personal email as another verified address before leaving.
