Just a reminder, because October is a long month and started on a weekend, the monthly calendar may not behave as expected on Sunday and Monday, especially if you use compressed weekends.

For more information, see

To enable or disable compressed weekends: right click on the 30 day calendar and choose Other settings. Add or remove the check from Compress weekend days.

Also - most areas in the US "fall back" this weekend. If your appointments are off by an hour beginning next week, especially on shared calendars, check the daylight time settings on all computers first.
