BASH SCRIPT - Insert date into cells in cvs file

Hi, I'm looking to accomplish the following.
Insert current date into three places/cells within a cvs, every time the bash script is executed.

The cells are column A,B,C row 2. Row 1 is reserved for the headers.

The file name is always orders.csv. These three cells we always have an old date so they need to be updated when the script is ran.

Thank you

You haven't shown any example of output or what you have tried on your own, so I give you this, based on your explanation.

perl -MPOSIX -ple '$_ = join ",",(strftime("%m/%d/%Y", localtime)) x 3 if $.==2' orders.csv
