Divide column 17 of table by 365

Hello, I have a 1500x15 table, how do I divide every element in the 15th column by 365? Or, how do I create a new column which is column 15 divided by 365?

y = x{:,15}./365
x{:,16} = y

Sorry, typo. It needs to be {} instead of () to extract from the table. See fix above.

More directly:
x.Var15 = x.Var15 / 365 % or whatever the 15th var is named
or
x.Var16 = x.Var15 / 365 % or whatever the new 16th var should be named
table brace subscripting is most useful for multiple variables, while the dot is more clear when there's only one.
Dividing by 365 sounds like a leap year bug just waiting to happen. Should you be using the calendar calculations built into datetime and calendarDuration?
