Gantt chart without specific calendar dates

[arhooley]

I need to chart a process that our organization performs quarterly. It
starts on a Thursday and ends Wednesday two weeks later (covers 14
days). It's cyclical and completely independent of specific dates.

Can I create a Gantt chart that just lets me show weekdays and not
dates? I managed to hide the columns showing Start and Finish dates and
un-protect the calendar dates to show days of the week instead, but
what about that "April 2005" that's completely irrelevant? Or what
about avoiding these workarounds altogether?

Thanks if anyone knows.
