Python | Pandas tseries.offsets.CustomBusinessHour

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.CustomBusinessHour() function is used to create your own custom business hours. DateOffset subclass representing possibly n custom business days.

Syntax: pandas.tseries.offsets.CustomBusinessHour() Parameter : n : int normalize : Normalize start/end dates to midnight before generating date range weekmask : weekmask of valid business days, passed to numpy.busdaycalendar holidays : None calendar : None start : start of business hour end : end of business hour offset : datetime.timedelta(0) Returns : offset

Example #1: Use pandas.tseries.offsets.CustomBusinessHour() function to create your own custom business hour offset. 

Python3

# importing pandas as pd
import pandas as pd

# Creating Timestamp
ts = pd.Timestamp('2019-4-23 11:15:00')

# Create an offset
cbh = pd.tseries.offsets.CustomBusinessHour(n = 2, weekmask = 'Mon Tue Wed Thu',
                                           start ='12:00')

# Print the Timestamp
print(ts)

# Print the Offset
print(cbh)

Output : Now we will add the offset to the given timestamp object to increment the datetime value. 

Python3

# Adding the offset to the given timestamp
new_timestamp = ts + cbh

# Print the updated timestamp
print(new_timestamp)

Output : As we can see in the output, we have successfully created an offset and added it to the given timestamp. Example #2: Use pandas.tseries.offsets.CustomBusinessHour() function to create your own custom business hour offset. 

Python3

# importing pandas as pd
import pandas as pd

# Creating Timestamp
ts = pd.Timestamp('2019-4-23 11:15:00')

# Create an offset
cbh = pd.tseries.offsets.CustomBusinessHour(start ='07:00', end ='14:00')

# Print the Timestamp
print(ts)

# Print the Offset
print(cbh)

Output : Now we will add the offset to the given timestamp object to increment the datetime value. 

Python3

# Adding the offset to the given timestamp
new_timestamp = ts + cbh

# Print the updated timestamp
print(new_timestamp)

Output : As we can see in the output, we have successfully created an offset and added it to the given timestamp.
