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.BusinessHour.isAnchored() function is used to check if the given offset is anchored or not.
Syntax: pandas.tseries.offsets.BusinessHour.isAnchored() Parameter : None Returns : boolean
Example #1: Use pandas.tseries.offsets.BusinessHour.isAnchored() function to check if the given offset object is anchored or not.
Python3
# importing pandas as pdimport pandas as pd# Creating Timestampts = pd.Timestamp('2019-10-10 11:15:00')# Create an offsetbh = pd.tseries.offsets.BusinessHour(n = 5)# Print the Timestampprint(ts)# Print the Offsetprint(bh) |
Output : 
Now we will add the Business hour offset to the given timestamp object to increment the datetime value. We will also check if the given offset is anchored or not.
Python3
# Adding the Business hour offset to the given timestampnew_timestamp = ts + bh# Print the updated timestampprint(new_timestamp)# check if the offset is# anchored or notresult = bh.isAnchored()# print the resultprint(result) |
Output : 
As we can see in the output, we have successfully created an offset and added it to the given timestamp. The function has returned False indicating that the given offset is not anchored. Example #2: Use pandas.tseries.offsets.BusinessHour.isAnchored() function to check if the given offset object is anchored or not.
Python3
# importing pandas as pdimport pandas as pd# Creating Timestampts = pd.Timestamp('2019-10-10 11:15:00')# Create an offsetbh = pd.tseries.offsets.BusinessHour(offset = datetime.timedelta(hours = 1))# Print the Timestampprint(ts)# Print the Offsetprint(bh) |
Output : 
Now we will add the Business hour offset to the given timestamp object to increment the datetime value. We will also check if the given offset is anchored or not.
Python3
# Adding the Business hour offset to the given timestampnew_timestamp = ts + bh# Print the updated timestampprint(new_timestamp)# check if the offset is# anchored or notresult = bh.isAnchored()# print the resultprint(result) |
Output : 
As we can see in the output, we have successfully created an offset and added it to the given timestamp. The function has returned True indicating that the given offset is anchored.
