Create a calendar on iCloud.com
You can create and manage one or more calendars and access them on any iPhone, iPad, iPod touch, Mac, or Windows computer that has iCloud Calendar turned on.

In Calendar on iCloud.com, click
in the bottom-left corner, then choose New Calendar.
Type a name for the calendar, then press Return or Enter.
Your calendars are listed in the sidebar on the left.
You can view as many calendars as you want at the same time.
iCloud Calendar includes two default calendars: Home and Work. You can rename or delete them, but you must always have at least one calendar in the list.
Thanks for your feedback.
