For example - an appointment scheduled for September 8th, 2026 at 5:00 PM.
Even thought the support docs say "Name of Month: {{appointment.month}}" when you actually render that, it comes out "Name of Month: 9"
A full example I did running the support table through an appointment description:
APPOINTMENT:
Appointment > Title: My Test Appointment
Appointment > Start Date Time: Friday, September 18, 2026 2:00 PM
Appointment > Start Date: September 18, 2026
Appointment > Start Time: 2:00 PM
Appointment > End Date Time: Friday, September 18, 2026 2:30 PM
Appointment > End Date: September 18, 2026
Appointment > End Time: 2:30 PM
Appointment > Day of the week:Friday
*->Appointment > Name of the month:9
