Countdown timer/clock on password page administrable

Investigating thoroughly and manage to make the code of the countdown counter manageable, when I reach the end I put a code to hide it, I’m still working on the beginning part, but it works to give you an end date

Name Sections: countdown-bar.liquid

{% if section.settings.enable_countdown %}

    

          {% for block in section.blocks  %}
