No.

In git, you have two type of date that keep track on your commit changes. Author date and Commit date. Author date is the actual date when changes are committed. Commit date could be change after rebase your branch.

Anyway, you can change both of these dates by using git command. Following command can change both commit date and author date for a given commit hash number.

git filter-branch -f --env-filter \
    'if [ $GIT_COMMIT = 943f032ac12f386ae6e9e9d14f9e1a4e269a16a4 ]
     then
         export GIT_AUTHOR_DATE=“Fri Jun 03 21:38:53 2016 -0800"
         export GIT_COMMITTER_DATE="Fri Jun 03 21:38:53 2016 -0800"
     fi'

So, you don't need to plan the date. You can try it now!
