Broken `cron` gh-action workflow

Question

I write as an exercise the GitHub action workflow below.

name: Cron CI
Controls when the workflow will run
on:
Triggers the workflow every day minutes
schedule:
    - cron: "01 10 * * 6,7"
    - cron: "01 10 * * 1,2,3,4,5"
A workflow run is made up of one or more jobs that can run sequentially or in parallel
jobs:
This workflow contains a single job called "cron"
cron:
    # The type of runner that the job will run on
    runs-on: ubuntu-latest
# Steps represent a sequence of tasks that will be executed as part of the job
steps:
  # Runs a single command using the runners shell
  - name: Run working script

    if: github.event.schedule != '01 10 * * 1,2,3,4,5'
    run: echo &quot;Wake up! Grab a brush and put a little makeup&quot;

  - name: Run resting script
    if: github.event.schedule != '01 10 * * 1,2,3,4,5'
    run: echo &quot;It's not time to make a change! Just relax, take it easy.&quot;

Although it seems correct to me, I receive the error log invalid cron attribute "01 10 * * 6,7". May you help me understand the error?

Cron schedules sometimes accept zero-filled integers (01), but not all do. — Kusalananda, Dec 30 '22 at 16:13
Linux cron allows either 0 or 7 for Sunday, but maybe yours doesn't. Why do you enumerate the weekdays if you want them all, anyway? — tripleee, Dec 30 '22 at 20:44
It is just a pun to echo different messages on working and leisure days. — Bruno Lobo, Dec 30 '22 at 20:51
It's not clear whether your response to my initial comment means that it works if you remove the leading zeroes on integers. — Kusalananda, Dec 30 '22 at 21:01
It did not work, as you can see here: https://github.com/trouchet/sappio/actions/runs/3808333270/workflow — Bruno Lobo, Dec 30 '22 at 22:12
I made modifications: 1. remove 0 digit; 2. use 0 as Sunday. Now it works. Great! — Bruno Lobo, Dec 30 '22 at 22:16
Probably post that as an answer and mark it as accepted (once you can). — tripleee, Dec 31 '22 at 07:48

I made following modifications:

Remove the initial digit 0.
Use 0 as Sunday instead of 7.

Now it works!
