Weekly Countdown 2.0 Script

So, this is a request, but there is already the OFA Timer, right? (The script mainly for OFA challenge)

But can there be a custom script for (ex. weekly trainings) so that when it goes zero, it started, but they can reserve for another training/event weekly?

Thanks,

P.S: You can think of something else, if you want related to it.
