Help combining calendar sheet with gannt chart sheet

Hello,

I am new to this forum and I was hoping to get some help with a challenge I am facing. I don't know if what I am trying to do is even possible but I wanted to give it a shot.

In the workbook attached below, I have a gannt chart on the sheet labeled "timeline overview' and a calendar on the sheet labeled "calendar". Ideally, I would like these two sheets to be connected. For example, setting the task start/end dates in the 'timeline overview' sheet would be represented in some way in the 'calendar' sheet. Or entering the task start/end date on the 'calendar' sheet would then correlate to the 'timeline overview' sheet.

Again, I am not sure if this is at all possible but I would appreciate any/all suggestions!!

Thanks,
Rachel
