# Update Cursor with Date Issue [closed]

My dates (maxDate, minDate, avgDate) all print out with the correct datetime format, but I am unsure if the problem is how the loop is written to update the cursor.

Error:

line 102, in updateRow return convertArcObjectToPythonObject(self._arc_object.UpdateRow(*gp_fixargs(args))) RuntimeError: ERROR 999999: Error executing function.

Code:

``````arcpy.env.workspace =  r"C:\ForChris\wetMatchs\SBA_wetlandTR_int\SBA.gdb"
fcs = arcpy.ListFeatureClasses()
years = []
yearsJD = []
for fc in fcs:

cursor = arcpy.SearchCursor(fc)
for row in cursor:
fDate = row.getValue("Final_Date")
a = (14 - fDate.month)//12 ## Julian date calc
y = fDate.year + 4800 - a
m = fDate.month + 12*a - 3
JD = fDate.day + ((153*m + 2)//5) + 365*y + y//4 - y//100 + y//400 - 32045
yearsJD.append(JD)
years.append(fDate)
averageJD = sum(yearsJD) / len(yearsJD) ## calculates average julian date
az = averageJD + 32044 ## convert julian date to calendar date
b = (4*az + 3)//146097
c = az - (146097*b)//4
d = (4*c + 3)//1461
e = c - (1461*d)//4
n = (5*e + 2)//153
aday = e + 1 - (153*n + 2)//5
amonth = n + 3 - 12*(n//10)
ayear = 100*b + d - 4800 + n/10
avgDate = datetime.datetime(ayear, amonth, aday)
minDate = numpy.min(years)
maxDate = numpy.max(years)

cursor2 = arcpy.UpdateCursor(fc)
for row2 in cursor2:
row2.setValue("Max_Year", maxDate)
row2.setValue("Min_Year", minDate)
row2.setValue("Avg_Year", avgDate)
cursor.updateRow(row2)
del years[0:len(years)] ### Empties List
del yearsJD[0:len(yearsJD)]
