The Calendar from iCloud is not showing on my iPhone.

If you mean that you don't see Calendars when using an internet browser on your phone, that is normal. See the iPhone section of Which iCloud.com features are available in the browser on your device - Apple Support

You should be able to see your Calendar information in the Calendar app on an iPhone.

In the Calendars app, tap on "calendars" in red at the bottom

Is your calendar checked on?

Hey pcaplan,

Good question!

If you don’t see a calendar you can follow these steps:

Click calendar at the bottom

Check if your calendar is on.

Thanks!

Why didn't I think of that?
