I add events to https://www.eventbrite.com/o/8157900344 on an ongoing basis for someone.

I would like to be reminded of the events 16-18 hours before the event, so I can check how many people signed up.

I have an AWS account, and know a bit about cron and having a process created and run every so often to do something, in this case, check for new events, and add them to my google calendar, with a reminder of, say, 18 hours, so I can be alerted, and do my check.

That's the concept.

How could I do this, and what program would I do it in?
