I have event website. I want send reminder about event exactly 2 hours before the event to subscribers.
So how can schedule wordpress to call the function exactly at time.
I know about wp_schedule and cron. But that doesn’t helps me.
Don’t recommend plugins. Because I am developing custom plugin. So what is the correct way to do that.
Example: if event start time is today 11:30 pm , I want to remind the event subscribers at exactly 9:30 pm.
