I’m looking for a way to visually (temporarily) mark a given day while zooming out to see the entire task or project

I have a project that spans 6 months.

Several tasks span five to six weeks.

I’m looking for a way to visually (temporarily) mark a given day while zooming out to see the entire task or project.

How can I see where a date falls. I often get an email saying. “I’ll have X ready early next week.” But looking at this chart I can’t even tell what day next week starts. I can magnify into “day” but then I can’t see the end of the task.
