Python Get Last Business Day

The last business day is the day when the trading of a given stock or other financial instrument closes. This is different from the expiration date, which is the last day that a security can be traded on an exchange.

The python get last business day of month is a python script that will return the last business day of the month. The script uses Python’s built-in datetime module.

Hey there! If you’re looking for a way to optimize your Python code, or just want to know when the next business day is, then this blog is for you!

Python has a built-in function that returns the next business day as a datetime object. This function is called ‘next_business_day’ and takes two arguments: the date argument and the timezone argument.

If you need to find out what day of the week it is on any given date, Pandas has a corresponding function called ‘weekday’. This function takes one parameter – a date string in ISO 8601 format.

The following example displays the weekday of November 15th, 2017 in both US/Eastern and UK/British Standard Time:

In [1]: today = datetime.datetime(2017, 11, 15) In [2]: weekday = pandas.weekday(today) Out[2]: u’Saturday’

Why do we need to get the last business day?

There are a few reasons why we might need to get the last business day of the month. For example, if we’re working on a project that requires us to invoice customers at the end of the month, we’ll need to make sure that we’re using the correct date so that our customers can receive their invoices on time. Additionally, if we’re keeping track of inventory or other data that changes on a daily basis, we may want to use the last business day as our “snapshot” date so that we can more accurately compare data from one month to another.

There are a few different ways to get the last business day of the month in Python. One option is to use the datetime module’s built-in calendar functions:

>>> import datetime

>>> last_business_day =, 8, 31) # August has 31 days

>>> while not last_business_day.isoweekday() in [6, 7]: # Saturday and Sunday are not business days

… last_business_day -= datetime.timedelta(days=1)

Python’s inbuilt libraries

Python’s inbuilt libraries offer a number of advantages over other programming languages. One of the main advantages is that they are constantly being updated and improved by the Python community. This means that new features are always available to developers, and bugs are quickly fixed.

Another advantage of using Python’s inbuilt libraries is that they are well-documented. This makes it easy for developers to find information about how to use them. There are also many online resources available which can help developers get started with using these libraries.

Finally, Python’s inbuilt libraries are reliable and robust. This means that developers can trust them to work correctly and reliably on their projects.

Using pandas

If you have a DataFrame with a column containing datetimes, you can use the .dt accessor to easily extract information about the dates, such as the day of the week or the month. This is especially useful when dealing with time series data. For example, say we have a DataFrame with columns “Date” and “Close”, which contains stock price data:

date = pd.date_range(‘1/1/2000’, periods=1000)

ts = Series(np.random.randn(1000), index=date)

Using workdays

If you’re like most people, you probably spend the majority of your weekdays working. But what if you need to take a day off for personal or professional reasons? How can you make sure that your work schedule doesn’t get too disrupted?

One way to do this is by using workdays. Workdays are days when you’re able to work, as opposed to weekends or holidays. You can use them to plan your week so that you have plenty of time for work and other obligations.

To get started, let’s take a look at how to find the next workday in Python. We’ll be using the datetime module for this purpose.

First, we need to import the datetime module:

>>> import datetime

Then, we can use the function to create a date object:

>>> today =, 1, 1) # New Year’s Day

Now that we have our date object, we can use the datetime.timedelta() function to add or subtract days from it:

>>> tomorrow = today + datetime.timedelta(days=1) # Add one day

>>> yesterday = today – datetime.timedelta(days=1) # Subtract one day

As you can see, adding or subtracting a timedelta from a date gives us another date object with the corresponding number of days added or subtracted. This is how we can find the next workday in Python:

>>> next_workday = today + datetime

Using timedelta

The timedelta class in the datetime module is used to represent differences in datetime objects. The class can be initialized with either two datetime objects or an integer value representing a number of days. When initializing with two datetime objects, the first object will be subtracted from the second and the resulting timedelta object will be returned. When initializing with an integer, a timedelta object will be created with that number of days as its delta attribute.

The timedelta class has several attributes that can be accessed to get information about the difference between two datetime objects. These include:

-days: The number of whole days represented by the timedelta object. This is equivalent to the delta attribute divided by 24 hours.

-seconds: The number of seconds represented by the timedelta object. This is equivalent to the delta attribute multiplied by 3600 seconds.

-microseconds: The number of microseconds represented by the timedelta object. This is equivalent to the delta attribute multiplied by 1 million microseconds.


Python is a powerful programming language that can be used for a wide range of tasks. In this article, we’ve looked at how to use Python to calculate the next business day, as well as how to get all Sundays between two dates. We’ve also seen how to use the pandas library to get the next business day.





The “python business days between two dates” is a command-line tool that allows users to get the last business day of the given date.
