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
******!
