yes, i use eZ Flow. I don't know what is "my calendar"
I was quoting you here, asking what you meant by "display my calendar into my FrontPage" ?
I just checked, there is no "Calendar" block in eZ Flow, but you can easily craft one. Here is more information on how to create an eZ Flow block : http://share.ez.no/learn/ez-publish/transforming-jquery-plugins-into-ez-publish-extensions/(page)/3 (do not mind the parts concerning transformation of the jQuery plugin).
Cheers,
