PHP Event Calendar packs with advanced features such as repeating events and event reminder. For event reminder works with hosts with cron job enabled to send out emails reminders time specified by users.
One or more emails are supported for event email reminders.
It’s required to setup a CRON job on your server for the following script. The CRON job will trigger the script to execute and find all the reminders and email them (Additional read: How to setup CRON job?).
