Syncing timed scripts

I’m making a Roblox game where there will be events every 150 seconds for 30 seconds, the only problem is that the 3 scripts I’m working to support this perodic event happen, need to happen at the the same time. What’s wrong is that I need the scripts to match but I really don’t know how. When I test the game, the scripts are unsynchronized and I don’t know how to synchronize them

I’ve tried searching on Youtube, DevForum, Google, ChatGPT, but I can’t find anything to help. What can I do to sync the scripts? If you want me to provide the scripts I’m referring, so that you can help modify it in anyway so they match, ask and I’ll reply with the code. (Also, I will admit, I used ChatGPT to make the codes because I can’t myself.)

Any help, will be appreciated.

The only way to fully synchronize them is to manage them all in one script and use a loop or some timer.
