Python | Pandas tseries.offsets.CustomBusinessDay.offset

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.CustomBusinessDay.offset returns a datetime.timedelta value. It is an alias for self._offset.

Syntax: pandas.tseries.offsets.CustomBusinessDay.offset

Parameter : None

Returns : self._offset

Example #1: Use pandas.tseries.offsets.CustomBusinessDay.offset attribute to return the self._offset of the given CustomBusinessDay offset object.

# importing pandas as pd
import pandas as pd
  
# Creating Timestamp
ts = pd.Timestamp('2019-4-23 11:15:00')
  
# Create an offset
cbd = pd.tseries.offsets.CustomBusinessDay(weekmask = 'Mon Tue Wed')
  
# Print the Timestamp
print(ts)
  
# Print the Offset
print(cbd)

Output :

Now we will add the offset to the given timestamp object to increment the datetime value. We will also print the self._offset value.
