Need Help Setting Up Reminder Before Appointment Date & Time

Hey,

We are trying to set up an automation that sends

a reminder before an appointment time. Here is what we currently have:
We save the appointment date and time in a custom field called appointments_date.

We created a rule that says:
“1 day after appointment_date at 00:00”
This runs our reminder automation.

But the problem is: this is not sending the reminder after or before.

For example, if someone books an appointment for July 22 at 9:00 AM, we want to send them a reminder 12 hours before (i.e., on July 21 at 9:00 PM).

Hey, ​@Turbo

There are a few things that you need to check:

  1. What happens if the user books an appointment in less than 24h (if possible)? There is a second rule?
  2. The checkmark “this event repeats every year” has to be active
