Is there a way to make a countdown timer (90 min) run across several web pages but not entire site without paying for an app?

I am not a coder but have figured out a 90 min countdown with redirect thanks to a wix user I found googling. I just can’t figure out how to make it show up on several pages and without restarting the time on each page…

Hello ashelfer,

perhaps this example will help you to realize your project…

Thanks. I had already looked at it. It helped me with the minutes/ seconds but not with showing the same timer across several web pages…
