Pandas dataframe change date from int64 to date in datetime

Question

I have a dataframe where the date column type is int64. I want to convert that column and its values to datetime.

df['datdadat'] = pd.to_datetime(df['datadate'].astype('str'), errors='coerce')

As you can see, my code fails when encountering the second row without leading zeroes for the months/days. I tried adding a format already, but when I add it in, even the first one with zeroes fails.

My question would be how to add in the leading zeroes before conversion, or if there is a good way to add a format in while converting it? Thx in advance

Answer 1

Try this:

df['datdadat'] = pd.to_datetime(df['datdadat'], format='%d%m%y')
print(df)

       datdadat
0 1984-01-30
1 1983-12-30
