Time expires

Hello guys,

I am currently trying to create a custom page template that is going to show content only when the countdown expires. I tried to put the shortcode on a conditional (do_shortcode[”]) but since it only verifies if the shortcode exists is always true even if the countdown expired. I was hoping to do something like this:
if (countdown still running){show countdown}else{show custom code}

Is there a way I can achieve this?

Please advise.

Thank you!
