Can't Change the timer

Trying to figure out how to change the timer to set a new time on the main page for event countdown. Ad well as the links for register now and get a ticket. Anyhelp would be greatly appreciated.

Search module "Header" with header position, there is a custom code, open in html view and change date.

Thanks worked like a charm

I tried this and it didn't work for me.
module:header:custom output:toggle editor

I changed the date here but the timer didn't change.

What did I do wrong?
