Trim the time from SharePoint DateTime column in SharePoint Designer

I was having the problem that SharePoint column was set to date only but when I used it in SPD workflows and sent emails and included this column in the emails, it put a timestamp of 12:00:00 on the column values. I had to use two datetime columns in my workflow to show duration of [DATE FROM] to [DATE TO]. In order to cut it, I created a calculated column and used the following formula and then I used the new column called "Duration" in my workflow.

=MONTH([Date From])&"/"&DAY([Date From])&"/"&YEAR([Date From])&" to "&MONTH([Date To])&"/"&DAY([Date To])&"/"&YEAR([Date To])

**[Date From] and [Date To] are columns of my SP list
