What would work in my opinion is this, if I understand you correctly:

1. In the Git repo of day 1, remove all files except for the .git 
folder. This is to make sure that any files that are no longer present 
on the next day are really no longer in the repo.

2. Copy the content of day 2 except the .git folder over into day 1. git 
status, git diff etc should show the differences between days 1 and 2.

3. Create a new branch for this day, and commit all changes.

4. Continue from step 1 for each remaining day.

This will result in one repository that has one commit per day. Going 
forward, you'd probably want to commit more often so that your commits 
comprise a meaningful unit of work instead of arbitrary day boundaries.

It does not matter that your system is air-gapped. Git works perfectly 
locally without ever fetching or pushing.

By the way, I don't think it's necessary to create a new branch each 
day; you can inspect the history just as well by only committing.
