WookiKent's answer is correct. To add to this however, if you're looking for some date object type attributes to extract year, month, day as ints, the following may be helpful:
dateObject:{`date`year`month`day!x,"I"$"."vs string[x]}
dt:dateObject[2000.02.01]
q)dt[`date]
2000.02.01
q)dt[`year]
2000
q)dt[`month]
2
q)dt[`day]
