why i can't convert from yyyy/mm/dd to time

[Jeon Joan]

hello
i have variable for time like this :

Day (variable name)
2011/12/01
2011/12/02
2011/12/03
.
.
2019/01/29

i want to convert this string variable to time for xtset
so, i did typing

gen Day2 = date(Day,"ymd")

but, i can't get any values
only get " . " in all cell

what is problem?

Stata commands are case sensitive. You need:

gen Day2 = date(Day,"YMD")
