Pandas: convert datetime to end-of-month

Pandas: convert datetime to end-of-month

In Pandas, you can convert a datetime column to the end of the month by using the pd.to_datetime() function in combination with the .dt accessor and the pd.offsets.MonthEnd object. Here's how you can do it:

import pandas as pd

# Create a DataFrame with a datetime column
data = {'date_column': ['2023-01-15', '2023-03-20', '2023-05-10']}
df = pd.DataFrame(data)

# Convert the date_column to datetime
df['date_column'] = pd.to_datetime(df['date_column'])

# Convert to end of the month
df['end_of_month'] = df['date_column'] + pd.offsets.MonthEnd(0)

# Print the result
print(df)

In this example:

  1. We create a DataFrame with a column named date_column containing date strings.

  2. We use pd.to_datetime() to convert the date_column to a datetime data type.

  3. We add the pd.offsets.MonthEnd(0) offset to each datetime value in the date_column. This offset calculates the end of the month for each date.

  4. The result is stored in a new column called end_of_month, which contains the end-of-month datetime values.

After running this code, the end_of_month column will contain datetime values representing the end of the corresponding month for each date in the date_column.
