add those two functions to your .bashrc:

function newbranch() {
    history_file=".git/branching_history"
    from=`git rev-parse --abbrev-ref HEAD`
    to=$1
    git checkout -b $1 > /dev/null 2>&1
    DATE=`date '+%Y-%m-%d %H:%M:%S'`
    echo "$DATE: from $from created branch $1" >> $history_file
}

function branchinghistory() {
    cat .git/branching_history
}

then when you create a new branch, don't run git checkout -b mybranch but do:

newbranch mybranch

this will store your branching log in .git/branching_history file. You can check the log with:

branchinghistory

the output should be:

2020-04-22 23:59:06: from master created branch mybranch
