Hi Jess,
Sorry no. Project is a scheduling tool and as such shows dates for all
tasks. A milestone task (0 duration) will show the same start and end
date/time, but non-the-less will still show a date.
If you want to just "hide" the date, you could change the font color to
white.
Perhaps if you tell us more about what you are trying to do, we can assist
further.
Hope this helps. Let us know how you get along.
Julie
