If you’ve ever tried to add a Calendar to your Publish SharePoint site running on the Office 365 P1 plan, you’ve probably noticed that it isn’t an option. However, with a little bit of work, you can get around it.
- Sign into your Public Facing Site, go to Site Settings and Site Content.
-
Add a “Custom List” App

- Give you custom list whatever name you want to use for the Calendar
-
Once the Custom list has been created, go to the list settings and click on advanced settings

-
Set “Allow Management of Content Types?” to Yes and click OK

-
In your list settings, you now have a section in the list for Content Types, click “Add from existing content types”

-
Select “Event”, Click Add>, Click OK

-
Go back to your custom list, and create a new view
-
Create a Calendar View and give it whatever name you wish

-
Give it whatever name and settings you want for the view (you need to set the Start Time, End Time and Titles), click OK

-
Now you have a Calendar!
