Firebase scheduler, service workers Functions push notifications

[Lx8 Co]

We are building a scheduler on Firebase with push notifications that will send a notification to a client 1 hour before an event. 

Anyone has an idea on how could we do it on Firebase, is it possible to use functions, service worker without any cron job?

Thanks!

I am also doing something very similar and I don't really know how to approach it at all. 

I basically need to say "Hit me with an Event on 23rd December at 11am".  I know this is not trivial. 

1. I considered the Google Calendar API but I struggle a bit with googles api and with a service account I couldn't find a great deal of information.
2. I looked at Firebase Functions, and like the entire Google Cloud Website, I have no idea what anything means or how it is relevant to me.  
3. I looked at `npm Agenda` and similar but then I was going down the road of needing Redis or Mongo which seems a whole new hassle. 
4. I also thought of cron, it just seems a little strange to use cron for a booking system, but since I have no experience in this, perhaps that is exactly what they are used for!

I hope we can get some insight.
