How to add custom calendar in Confluence

[mayuresh athalekar]

I am facing major concern with managing the team schedule / planning on confluence

1. My company central administration has not enabled & will not enabled calendar in confluence due to some policies.

2. I am in need of adding a planning page where it is getting increasingly difficult to add any customized table kind of model

Anyone has workaround to include a good planning / calendar (not standard plug-in) ?
