How to convert a leapyear date into datetime in a For loop?

Question

I am using a for loop to convert all the date in the dataframe to datetime. But since one of the date is in leap year it is giving the error.

DeciYear = []
for i in range(0,len(data_ncs)):
   print(i) 
   d=datetime(data_ncs.Year.iloc[i],data_ncs.Month.iloc[i],data_ncs.Day.iloc[i],data_ncs.Hour.iloc[i],    data_ncs.Minute.iloc[i],int(data_ncs.Seconds.iloc[i])) 
 

ERROR:

ValueError: day is out of range for month

The date which is causing the error datetime(1991,2,29,12,12,12) How come I could override this error?
