“How To Convert A Python Datetime.Datetime To Excel Serial Date Number” ~ bbaz
Introduction
As a Python programmer, you might have struggled with the daunting task of converting a datetime object into an Excel serial date number. This task can be time-consuming and often requires the use of complex codes. However, there’s good news! In this article, we’ll provide you with simple tips and tricks to help you achieve this conversion seamlessly.
Understanding Datetime and Excel Serial Date Numbers
Before we dive into the solution to convert a datetime object into an Excel serial date number, let’s first clearly understand what these two terminologies mean.
A datetime object is a date and time representation in Python that consists of year, month, day, and time information. On the other hand, an Excel serial date number is a numeric value that represents a date in Excel. It is calculated by counting the number of days between a fixed date (December 30, 1899) and the given date.
The Solution
The solution to convert a datetime object into an Excel serial date number is relatively simple. You can use the xlwt library in Python, which provides the XFStyle module to format the output as a serial date number.
To implement this solution, you need to use the following code:
import xlwtfrom datetime import datetimestyle = xlwt.XFStyle()style.num_format_str = 'M/D/YY'date_string = '12/19/98'date_object = datetime.strptime(date_string, '%m/%d/%y')serial_date_number = xlwt.Utils.datetime_to_serial(date_object, 0)print(serial_date_number)
In this code block, we first import the necessary libraries – xlwt and datetime. We then use the XFStyle module to format the output as a serial date number. Next, we define our date string and convert it into a datetime object using the strptime() method. Finally, we use the datetime_to_serial() method to get the serial date number of the converted date object.
Comparison Table
Let’s compare the pros and cons of using different Python libraries to convert a datetime object into an Excel serial date number.
| Library | Pros | Cons |
|---|---|---|
| xlwt | Easy to use, provides formatting options | Limited functionality, only supports writing to Excel |
| openpyxl | Supports reading and writing to Excel, extensive functionality | Steep learning curve, complex code |
| pandas | High performance, advanced data analysis, supports multiple file formats | Requires large amounts of memory, not suitable for small datasets |
Conclusion
Converting a datetime object into an Excel serial date number is no longer a cumbersome task. With the simple tips and tricks mentioned in this article, you can easily achieve this conversion in just a few lines of code. However, it’s essential to understand the library options available and choose the one that best suits your requirements.

Here are some frequently asked questions about converting a datetime object to an Excel serial date number in Python:
- What is a datetime object in Python?
- What is an Excel serial date number?
- How do I convert a datetime object to an Excel serial date number?
- Can I use this function for dates before 1900?
- Is there a built-in function in Python to convert datetime objects to Excel serial date numbers?
A datetime object is a built-in Python module that represents a date and time. It includes attributes such as year, month, day, hour, minute, second, and microsecond.
An Excel serial date number is the number of days between January 1, 1900 (which is considered day 1) and a specific date. For example, January 2, 1900 has a serial date number of 2.
Here’s an example code snippet:
“` import datetime import xlrd def datetime_to_excel_serial(date): temp = datetime.datetime(1899, 12, 30) delta = date – temp return float(delta.days) + (float(delta.seconds) / 86400) date = datetime.datetime.now() serial = datetime_to_excel_serial(date) print(serial) “`
This will output the current date and time in serial date number format.
No, this function assumes that the date is after December 30, 1899. Excel doesn’t support dates before this time.
No, there isn’t a built-in function. You’ll need to use a custom function like the one shown above.
