π‘ Problem Formulation: When working with time series data in Python, a common operation is to modify or floor the resolution of timedelta objects. Specifically, we may want to truncate a timedelta to a minutely resolution, so that any smaller time units (seconds or milliseconds) are disregarded. For instance, if the input is Timedelta('0 days 00:05:45.123456')
, the desired output is Timedelta('0 days 00:05:00')
, representing a floored timedelta to the nearest minute.
Method 1: Using floor Function
This method utilizes the floor()
function provided by the Timedelta
object in pandas. It allows for rounding down the timedelta to a specified frequency. The pandas Timedelta
class can parse and output a floored object when given an appropriate frequency string such as ‘T’ for minutes.
Here’s an example:
import pandas as pd # Creating Timedelta Series times = pd.Series([pd.Timedelta('0 days 00:05:45.123456')]) # Use apply with a lambda to floor each timedelta floored_times = times.apply(lambda td: td.floor('T')) print(floored_times)
0 0 days 00:05:00 dtype: timedelta64[ns]
In one line of code, we apply a lambda function that calls the floor method with ‘T’ (minute) frequency on each Timedelta
in the Series. This is a quick and flexible solution for applying complex operations to Series elements.
Summary/Discussion
- Method 1: Using floor Function. Straightforward and concise. It applies to single Timedelta objects and Series via .dt accessor.
- Method 2: Timedelta Components Manipulation. Manipulates raw Timedelta components, offering fine control. More verbose and less intuitive than other methods.
- Method 3: Using to_pydatetime and timedelta. Combines pandas and Python’s native datetime modules, increasing complexity but also interoperability with other datetime modules.
- Method 4: Using dt Accessor Floor Method. Ideal for Series of Timedeltas. Vectorized for efficiency, but only applicable to Series, not individual Timedeltas.
- Method 5: Using a Lambda Function. Versatile and compact for Series. The syntax may be less clear to those not familiar with lambda functions.
import pandas as pd # Creating Timedelta Series times = pd.Series([pd.Timedelta('0 days 00:05:45.123456')]) # Floor the whole series to nearest minute floored_times = times.dt.floor('T') print(floored_times)
0 0 days 00:05:00 dtype: timedelta64[ns]
This example showcases how to floor an entire Series of Timedelta
objects to a minutely resolution all at once. The .dt.floor('T')
method is the vectorized equivalent for Series to the scalar floor()
method discussed earlier.
Bonus One-Liner Method 5: Using a Lambda Function
A one-liner approach utilizes a lambda function within the apply()
method on a Series to achieve minute floored resolution. This method is both succinct and powerful.
Here’s an example:
import pandas as pd # Creating Timedelta Series times = pd.Series([pd.Timedelta('0 days 00:05:45.123456')]) # Use apply with a lambda to floor each timedelta floored_times = times.apply(lambda td: td.floor('T')) print(floored_times)
0 0 days 00:05:00 dtype: timedelta64[ns]
In one line of code, we apply a lambda function that calls the floor method with ‘T’ (minute) frequency on each Timedelta
in the Series. This is a quick and flexible solution for applying complex operations to Series elements.

import pandas as pd # Creating Timedelta Series times = pd.Series([pd.Timedelta('0 days 00:05:45.123456')]) # Use apply with a lambda to floor each timedelta floored_times = times.apply(lambda td: td.floor('T')) print(floored_times)
0 0 days 00:05:00 dtype: timedelta64[ns]
In one line of code, we apply a lambda function that calls the floor method with ‘T’ (minute) frequency on each Timedelta
in the Series. This is a quick and flexible solution for applying complex operations to Series elements.
Summary/Discussion
- Method 1: Using floor Function. Straightforward and concise. It applies to single Timedelta objects and Series via .dt accessor.
- Method 2: Timedelta Components Manipulation. Manipulates raw Timedelta components, offering fine control. More verbose and less intuitive than other methods.
- Method 3: Using to_pydatetime and timedelta. Combines pandas and Python’s native datetime modules, increasing complexity but also interoperability with other datetime modules.
- Method 4: Using dt Accessor Floor Method. Ideal for Series of Timedeltas. Vectorized for efficiency, but only applicable to Series, not individual Timedeltas.
- Method 5: Using a Lambda Function. Versatile and compact for Series. The syntax may be less clear to those not familiar with lambda functions.
import pandas as pd # Creation of original Timedelta original_td = pd.Timedelta('0 days 00:05:45.123456') # Floor to nearest minute floored_td = original_td.floor('T') print(floored_td)
0 days 00:05:00
This snippet creates a Timedelta
object representing a duration of 5 minutes, 45 seconds, and some microseconds. Applying the floor('T')
method truncates the timestamp to the nearest minute, effectively zeroing seconds and microseconds.
Method 2: Timedelta Components Manipulation
A direct approach for minutely floored resolution is to manually adjust the components of Timedelta object. The Timedelta
object in pandas has properties like seconds
which can be used for this manipulation.
Here’s an example:
import pandas as pd # Creating a Timedelta object original_td = pd.Timedelta('0 days 00:05:45.123456') # Manipulate the seconds to floor to minutes floored_td = pd.Timedelta(minutes=original_td.components.minutes) print(floored_td)
0 days 00:05:00
Here, we decompose the Timedelta
into its component parts and rebuild it, discarding any smaller than minute units. This gives us a new Timedelta
precisely floored to minutely resolution.
Method 3: Using to_pydatetime and timedelta
Conversion to Python’s native datetime.timedelta
object and truncating the seconds can also floor a pandas Timedelta
to a minutely resolution. This method involves using the to_pydatetime()
method.
Here’s an example:
import pandas as pd from datetime import timedelta # Creating a Timedelta object original_td = pd.Timedelta('0 days 00:05:45.123456') # Convert and floor to nearest minute floored_td = timedelta( minutes=original_td.to_pytimedelta().seconds // 60 ) print(pd.Timedelta(floored_td))
0 days 00:05:00
By converting a pandas Timedelta
to the standard library’s timedelta
, rounding down the seconds, and converting back to a pandas Timedelta
, this approach achieves minute resolution. Note that one must handle seconds conversion properly to avoid issues with days in the Timedelta
.
Method 4: Using dt Accessor Floor Method
Pandas Series objects with datetime-like values provide the .dt
accessor for date and time properties and methods, including floor
. This is highly efficient when working with Series containing timedelta values.
Here’s an example:
import pandas as pd # Creating Timedelta Series times = pd.Series([pd.Timedelta('0 days 00:05:45.123456')]) # Floor the whole series to nearest minute floored_times = times.dt.floor('T') print(floored_times)
0 0 days 00:05:00 dtype: timedelta64[ns]
This example showcases how to floor an entire Series of Timedelta
objects to a minutely resolution all at once. The .dt.floor('T')
method is the vectorized equivalent for Series to the scalar floor()
method discussed earlier.
Bonus One-Liner Method 5: Using a Lambda Function
A one-liner approach utilizes a lambda function within the apply()
method on a Series to achieve minute floored resolution. This method is both succinct and powerful.
Here’s an example:
import pandas as pd # Creating Timedelta Series times = pd.Series([pd.Timedelta('0 days 00:05:45.123456')]) # Use apply with a lambda to floor each timedelta floored_times = times.apply(lambda td: td.floor('T')) print(floored_times)
0 0 days 00:05:00 dtype: timedelta64[ns]
In one line of code, we apply a lambda function that calls the floor method with ‘T’ (minute) frequency on each Timedelta
in the Series. This is a quick and flexible solution for applying complex operations to Series elements.

- Method 2: Timedelta Components Manipulation. Manipulates raw Timedelta components, offering fine control. More verbose and less intuitive than other methods.
- Method 3: Using to_pydatetime and timedelta. Combines pandas and Python’s native datetime modules, increasing complexity but also interoperability with other datetime modules.
- Method 4: Using dt Accessor Floor Method. Ideal for Series of Timedeltas. Vectorized for efficiency, but only applicable to Series, not individual Timedeltas.
- Method 5: Using a Lambda Function. Versatile and compact for Series. The syntax may be less clear to those not familiar with lambda functions.
import pandas as pd # Creating a Timedelta object original_td = pd.Timedelta('0 days 00:05:45.123456') # Manipulate the seconds to floor to minutes floored_td = pd.Timedelta(minutes=original_td.components.minutes) print(floored_td)
0 days 00:05:00
Here, we decompose the Timedelta
into its component parts and rebuild it, discarding any smaller than minute units. This gives us a new Timedelta
precisely floored to minutely resolution.
Method 3: Using to_pydatetime and timedelta
Conversion to Python’s native datetime.timedelta
object and truncating the seconds can also floor a pandas Timedelta
to a minutely resolution. This method involves using the to_pydatetime()
method.
Here’s an example:
import pandas as pd from datetime import timedelta # Creating a Timedelta object original_td = pd.Timedelta('0 days 00:05:45.123456') # Convert and floor to nearest minute floored_td = timedelta( minutes=original_td.to_pytimedelta().seconds // 60 ) print(pd.Timedelta(floored_td))
0 days 00:05:00
By converting a pandas Timedelta
to the standard library’s timedelta
, rounding down the seconds, and converting back to a pandas Timedelta
, this approach achieves minute resolution. Note that one must handle seconds conversion properly to avoid issues with days in the Timedelta
.
Method 4: Using dt Accessor Floor Method
Pandas Series objects with datetime-like values provide the .dt
accessor for date and time properties and methods, including floor
. This is highly efficient when working with Series containing timedelta values.
Here’s an example:
import pandas as pd # Creating Timedelta Series times = pd.Series([pd.Timedelta('0 days 00:05:45.123456')]) # Floor the whole series to nearest minute floored_times = times.dt.floor('T') print(floored_times)
0 0 days 00:05:00 dtype: timedelta64[ns]
This example showcases how to floor an entire Series of Timedelta
objects to a minutely resolution all at once. The .dt.floor('T')
method is the vectorized equivalent for Series to the scalar floor()
method discussed earlier.
Bonus One-Liner Method 5: Using a Lambda Function
A one-liner approach utilizes a lambda function within the apply()
method on a Series to achieve minute floored resolution. This method is both succinct and powerful.
Here’s an example:
import pandas as pd # Creating Timedelta Series times = pd.Series([pd.Timedelta('0 days 00:05:45.123456')]) # Use apply with a lambda to floor each timedelta floored_times = times.apply(lambda td: td.floor('T')) print(floored_times)
0 0 days 00:05:00 dtype: timedelta64[ns]
In one line of code, we apply a lambda function that calls the floor method with ‘T’ (minute) frequency on each Timedelta
in the Series. This is a quick and flexible solution for applying complex operations to Series elements.

import pandas as pd # Creation of original Timedelta original_td = pd.Timedelta('0 days 00:05:45.123456') # Floor to nearest minute floored_td = original_td.floor('T') print(floored_td)
0 days 00:05:00
This snippet creates a Timedelta
object representing a duration of 5 minutes, 45 seconds, and some microseconds. Applying the floor('T')
method truncates the timestamp to the nearest minute, effectively zeroing seconds and microseconds.
Method 2: Timedelta Components Manipulation
A direct approach for minutely floored resolution is to manually adjust the components of Timedelta object. The Timedelta
object in pandas has properties like seconds
which can be used for this manipulation.
Here’s an example:
import pandas as pd # Creating a Timedelta object original_td = pd.Timedelta('0 days 00:05:45.123456') # Manipulate the seconds to floor to minutes floored_td = pd.Timedelta(minutes=original_td.components.minutes) print(floored_td)
0 days 00:05:00
Here, we decompose the Timedelta
into its component parts and rebuild it, discarding any smaller than minute units. This gives us a new Timedelta
precisely floored to minutely resolution.

import pandas as pd from datetime import timedelta # Creating a Timedelta object original_td = pd.Timedelta('0 days 00:05:45.123456') # Convert and floor to nearest minute floored_td = timedelta( minutes=original_td.to_pytimedelta().seconds // 60 ) print(pd.Timedelta(floored_td))

, rounding down the seconds, and converting back to a pandas Timedelta
