I think this is what you are asking:

******!
clear
inp  str12(Date1          Date2         Date3         Date4)
23July1997    01Jan1997     12Sept1997     03Feb1997
05July1997	04July1997	03July1997	02July1997
end

ds
foreach v in `r(varlist)' {
	g `v'2 = date(`v', "DMY")
	format `v'2 %td
	drop `v'
	rename `v'2 `v'
		}
	g id = _n
reshape long Date, i(id) j(n)
sort Date
g new = _n
drop n id
g id = 1
reshape wide Date, i(id) j(new)
drop id
li
******!
