Timeline without dates?

[Jeb Raitt]

This topic was discussed in an earlier thread but it's dormant so I'm starting a new one.  Hope this is the correct board for this question

Using Visio Professional 2016, my client wants a timeline with sequential days instead of calendar dates.

I downloaded the shapes Paul Heber created, but they don't work, probably because they were designed for an earlier version.

Though a longtime Visio user, I've never delved into the Shapesheets.

is there a path to follow for this sort of design?

Is there a way to format dates as sequential days using visBEMask?
