Syncing your reminders with your personal calendar is quite trivial.

When creating a new reminder, after you set all the properties for you reminder, tap “Add reminder to calendar” toggle. It will prompt you to choose which calendar you want your reminder to sync with. When you press save, that reminder will appear in your personal calendar and repeat in your personal calendar for however long you decided the reminder to send.

If you end up deleting the reminder, it will delete from your personal calendar also.
