How to revert git branch with all commits?

Question

I was deleted my barnch form Github Branch Page. What i did before deleted my branch?

1. Resetup my ubuntu os, git SSH keys, downloaded repo zip file.
2. Extract the zip file.Then added remote url.
3. Then push it to main.

After that a checked my repo.Main converted to master because perviously there was a main branch. I then i thoguht main is alrady there so i can delete master.I deleted master branch and then my all 75 commits deleted from history.

My all data avaliable in newly created branch.But want to get back my 30 days commits history

After download Zip file and commit history. `

This is a good starting point. You can create a branch for this commit

git branch one_day_ago 361022eb

and I guess that would bring back most of the 75 commits.

Git does not immediately purge from disk commits that are no longer referenced by any branch/tag, they are garbage collected after 4 weeks or something like that.

There is also git reflog mechanism that keeps track of what you have worked with, and it might contain newer commits than 361022eb as well.

For a convenient way of inspecting the reflog you can launch gitk with the --reflog argument.
