Calendar online (similar to quickchart.io)

Hi everyone,
I have already looked into the community but everything i found doesn’t really help me.

I would need to create a Calendar Online (similar concept of quickchart.io), I’m currently using Google Calendar and it works good but i dont like much the template. I’m sure there’s something nicer.
I looked already the “Create a Calendar 2020” post, but i dont want to create buttons, i’d like just to use a template from a link (exactly how quickchat.io works with graphs).

Anyone who has any idea?
Thank you very much

Seems like I found something good using Airtable.
But still open to new discoveries!
