Introduction

Python is one of the most popular programming languages in data science and analysis. Pandas, a powerful library for data manipulation, has become an essential tool for working with data in Python. However, getting the business days between two dates using Pandas can be confusing at times. In this article, we’ll walk you through the process of calculating business days and provide you with code examples that you can use right away.

What Are Business Days?

Business days are the standard workdays – Monday till Friday – used by businesses for regular operations. This excludes weekends and public holidays. Many calculations in finance and economics revolve around business days since they have a significant impact on market behavior. It’s crucial to take those into account when analyzing financial data.

Calculating Business Days Using Pandas

The Pandas library provides built-in functions for business day frequency. The B frequency offset represents business days. The B can similarly manage holidays and weekends as trading days according to specific countries or regions. Combining these tools allows us to calculate the number of business days between two dates accurately.

Basic Calculation

To calculate the number of business days between two dates, we can use the bdate_range() method. This method will return a range of business dates between two given dates. We can then use the len() function to count the number of business days in the range.

Input Output
import pandas as pd
from pandas.tseries.offsets import BDay
start_date = pd.to_datetime('2022-01-01')
end_date = pd.to_datetime('2022-01-10')
business_days = pd.bdate_range(start_date, end_date, freq='B')
print(len(business_days))

Handling Holidays and Weekends

In many countries, there are more holidays than just weekends. The BDay() function can take a list of holiday dates as input to exclude those dates during day calculation. Additionally, in some cases such as the Middle East, the workweek may be five days, but it falls from Sunday to Thursday. In such circumstances, the default business day frequency is not applied. However, the frequency applies by customizing the weekends as days off.

Input Output
import pandas as pd
from pandas.tseries.offsets import CustomBusinessDay
from pandas.tseries.holiday import USFederalHolidayCalendar
us_cal = USFederalHolidayCalendar()
my_weekends = ['Saturday', 'Sunday']
cb = CustomBusinessDay(calendar=us_cal, weekmask=my_weekends)
start_date = pd.to_datetime('2022-01-01')
end_date = pd.to_datetime('2022-01-10')
holiday_dates = ['2022-01-03']
business_days = pd.date_range(start_date, end_date, freq=cb, holidays=holiday_dates)
print(len(business_days))

Round Trips Calculation

The bdate_range() function can handle dates or datetimes as inputs. However, when the input is a timestamp, the output will vary differently depending on whether we pass them as strings or as a timestamp object. As seen in the example below, when we pass the start and end dates as string objects, it only returns four business days. This result because the timedelta function does not add an additional day. To fix this, we can pass the values as datetime objects.

Input Output
import pandas as pd
from pandas.tseries.offsets import BDay
start_date = pd.to_datetime('2022-01-01 12:00:00')
end_date = pd.to_datetime('2022-01-09 12:00:00')
business_days = pd.bdate_range(start_date, end_date, freq='B')
print(len(business_days))
4
import pandas as pd
from pandas.tseries.offsets import BDay
start_date = pd.Timestamp('2022-01-01 12:00:00')
end_date = pd.Timestamp('2022-01-09 12:00:00')
business_days = pd.bdate_range(start_date, end_date, freq='B')
print(len(business_days))

Here are some frequently asked questions about getting business days between start and end date using pandas:

  1. What is pandas?

    Pandas is an open-source data manipulation and analysis library that provides data structures for efficiently storing and analyzing large datasets.

  2. What are business days?

    Business days refer to the weekdays from Monday to Friday, excluding weekends and public holidays.

  3. How do I get business days between start and end date using pandas?

    You can use the pandas bdate_range function to generate a range of business days between the start and end date. Then, you can find the length of the resulting range to get the number of business days.

  4. Can I include public holidays in the calculation?

    Yes, you can include public holidays by passing a custom holiday calendar to the bdate_range function.

  5. What if my start and end dates are not weekdays?

    The bdate_range function automatically adjusts the start and end dates to the nearest weekday before generating the range of business days.

In summary, pandas provides a convenient way to calculate the number of business days between two dates. By using the bdate_range function and a custom holiday calendar, you can easily customize the calculation to suit your needs.
