We have a great custom tool that allows you to change multiple Project Start Dates – so if you are interested in that … Contact Us.
However this question was around Changing Task Start Dates.
In Project, select all the Start Dates that you want to make the same date
Then Right-Click and choose Information… and select the start date and choose OK.
You will see that the Start Dates change.
Enjoy.
