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. DateOffsets 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.copy() function returns a copy of the given Business day offset object.
Syntax: pandas.tseries.offsets.BusinessDay.copy() Parameter : None Returns : returns a copy
Example #1: Use pandas.tseries.offsets.BusinessDay.copy() function to create a copy of the given offset object.
Python3
# importing pandas as pdimport pandas as pd# Creating Timestampts = pd.Timestamp('2019-10-10 07:15:11')# Create an offset of 5 Business daysbd = pd.tseries.offsets.BusinessDay(n = 5)# Print the Timestampprint(ts)# Print the DateOffsetprint(bd) |
Output : 
Now we will add the Business day offset to the given timestamp object to increment the datetime value. We will also create a copy of the given offset object.
Python3
# Adding the Business day offset to the given timestampnew_timestamp = ts + bd# Print the updated timestampprint(new_timestamp)# create a copy of the given# offset objectbd_copy = bd.copy()# Check if the two objects are# same or notprint(bd_copy is bd) |
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. We have also created a copy of the given offset object. Example #2 : Use pandas.tseries.offsets.BusinessDay.copy() function to create a copy of the given offset object.
Python3
# importing pandas as pdimport pandas as pd# Creating Timestampts = pd.Timestamp('2019-10-10 07:15:11')# Create an offset of 10 Business days and 10 hoursbd = pd.tseries.offsets.BusinessDay(offset = datetime.timedelta(days = 10, hours = 10))# Print the Timestampprint(ts)# Print the DateOffsetprint(bd) |
Output : 
Now we will add the Business day offset to the given timestamp object to increment the datetime value. We will also create a copy of the given offset object.
Python3
# Adding the Business day offset to the given timestampnew_timestamp = ts + bd# Print the updated timestampprint(new_timestamp)# create a copy of the given# offset objectbd_copy = bd.copy()# Check if the two objects are# same or notprint(bd_copy is bd) |
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. We have also created a copy of the given offset object.
