ValueError: NaTType does not support utcoffset error occurs in Python when “you try to set the utcoffset property of a NaTType object.”
A NaTType object is a particular datetime object representing a missing date or time. It does not have a timezone, so it does not have a utcoffset property.
NaT is used to represent missing or null datetime values in Pandas.
When working with pandas in Python, especially with datetime-like objects containing a NaT (“Not a Time”).
How to fix it?
Here are two ways to fix the ValueError: NaTType does not support utcoffset error.
- Drop the NaT values
- Fill in the NaT values
Solution 1: Drop the NaT values
To drop the NaT values from Series or DataFrame, you can “use the dropna() method.”
For Series
import pandas as pd
# Sample Series with NaT values
s = pd.Series([pd.Timestamp('2023-01-01'), pd.NaT,
pd.Timestamp('2023-01-03')])
# Drop NaT values
s = s.dropna()
print(s)
Output
0 2023-01-01
2 2023-01-03
dtype: datetime64[ns]
For DataFrame
import pandas as pd
# Sample DataFrame with NaT values in 'dates' column
df = pd.DataFrame({
'dates': [pd.Timestamp('2023-01-01'), pd.NaT, pd.Timestamp('2023-01-03')],
'values': [10, 20, 30]
})
# Drop NaT values
df = df.dropna()
print(df)
Output
dates values
0 2023-01-01 10
2 2023-01-03 30
Solution 2: Fill in the NaT values
To fill the NaT values instead of dropping them, you can “use the fillna() method.”
For Series
import pandas as pd
# Sample Series with NaT values
s = pd.Series([pd.Timestamp('2023-01-01'), pd.NaT,
pd.Timestamp('2023-01-03')])
s = s.fillna(pd.Timestamp('2023-01-01'))
print(s)
Output
0 2023-01-01
1 2023-01-01
2 2023-01-03
dtype: datetime64[ns]
For DataFrame
import pandas as pd
# Sample DataFrame with NaT values in 'dates' column
df = pd.DataFrame({
'dates': [pd.Timestamp('2023-01-01'), pd.NaT, pd.Timestamp('2023-01-03')],
'values': [10, 20, 30]
})
df['dates'] = df['dates'].fillna(pd.Timestamp('2023-01-01'))
print(df)
Output
dates values
0 2023-01-01 10
1 2023-01-01 20
2 2023-01-03 30
Conclusion
By dropping or filling the NaT values, you ensure that subsequent operations on the datetime-like objects won’t face the “NaTType does not support utcoffset” error.
