Hi @sphynxma,
Hope you are doing well.
Yes, using the SchedulePress plugin you can schedule The Events Calendar post as well. To do this you need to allow post-event calendar’s post type from SchedulePress settings. You can check this doc to know how you can allow a post type.
After allowing the post type you can schedule your events and share them on social media using the SchedulePress plugin. You can check this screencast.
Hope this will help you. If still, you need any help, feel free to reach us here, our team will help you, so don’t worry.
Thanks!
