Excel datetime format refers to the way dates and times are represented in Microsoft Excel. In this format, dates are represented as whole numbers while times are represented as decimal numbers.
In Python, the datetime
module provides various functions to work with date and time values. The datetime
module also provides a method to convert Excel datetime values to Python datetime objects.
To convert an Excel datetime value to a Python datetime object, you can use the following code:
import datetime
def excel_to_datetime(excel_date):
if excel_date > 59:
excel_date -= 1 # Excel leap year bug, 1900 is not a leap year!
return (datetime.datetime(1899, 12, 31) + datetime.timedelta(days=excel_date)).replace(microsecond=0)
This code takes an Excel datetime value as input and returns a Python datetime object without microseconds.
To convert a Python datetime object to an Excel datetime value, you can use the following code:
def datetime_to_excel(dt):
delta = dt - datetime.datetime(1899, 12, 31)
return delta.days + delta.seconds / 86400 + delta.microseconds / 86400e6
This code takes a Python datetime object as input and returns an Excel datetime value.
Overall, if you are working with Excel datetime values in Python, you can rely on the datetime
module to easily convert between the two formats.
