Python | Pandas tseries.offsets.BusinessDay

  • Last Updated : 23 Apr, 2019

Dateoffsets are a standard kind of date increment used for a date range in Pandas. It works exactly like relativedelta in terms of the keyword args we pass in. DateOffets work as follows, each offset specify a set of dates that conform to the DateOffset. For example, Bday defines this set to be the set of dates that are weekdays (M-F).

DateOffsets can be created to move dates forward a given number of valid dates. For example, Bday(2) can be added to a date to move it two business days forward. If the date does not start on a valid date, first it is moved to a valid date and then offset is created.

Pandas tseries.offsets.BusinessDay() function to create a Business day offset.

Syntax: pandas.tseries.offsets.BusinessDay()

Parameter :
n : The number of time periods the offset represents.
normalize : Whether to round the result of a DateOffset addition down to the previous midnight.
offset : datetime.timedelta(0)

Returns : Business day offset

Example #1: Use pandas.tseries.offsets.BusinessDay() function to create an offset of 5 Business days.




# importing pandas as pd
import pandas as pd
  
# Creating Timestamp
ts = pd.Timestamp('2019-10-10 07:15:11')
  
# Create an offset of 5 Business days
bd = pd.tseries.offsets.BusinessDay(n = 5)
  
# Print the Timestamp
print(ts)
  
# Print the DateOffset
print(bd)

Output :

Now we will add the Business day offset to the given timestamp object to increment the datetime value.




# Adding the Business day offset to the given timestamp
new_timestamp = ts + bd
  
# Print the updated timestamp
print(new_timestamp)

Output :

As we can see in the output, we have successfully created an offset of 5 Business days and added it to the given timestamp.

Example #2 : Use pandas.tseries.offsets.BusinessDay() function to create an offset of 10 Business days and 10 hours.




# importing pandas as pd
import pandas as pd
  
# Creating Timestamp
ts = pd.Timestamp('2019-10-10 07:15:11')
  
# Create an offset of 10 Business days and 10 hours
bd = pd.tseries.offsets.BusinessDay(offset = datetime.timedelta(days = 10, hours = 10))
  
# Print the Timestamp
print(ts)
  
# Print the DateOffset
print(bd)

Output :

Now we will add the Business day offset to the given timestamp object to increment the datetime value.




# Adding the Business day offset to the given timestamp
new_timestamp = ts + bd
  
# Print the updated timestamp
print(new_timestamp)

Output :

As we can see in the output, we have successfully created an offset of 10 Business days & 10 hours and added it to the given timestamp.
