Python Pandas - Get the weekmask applied on the CustomBusinessDay offset

To get the weekmask applied on the CustomBusinessDay offset, use the CustomBusinessDay.weekmask property in Pandas.

At first, import the required libraries −

import pandas as pd

Set the timestamp object in Pandas −

timestamp = pd.Timestamp('2021-10-22 03:10:35')

Create the CustomBusinessDay Offset. CustomBusinessDay is the DateOffset subclass representing custom business days excluding holidays. Weekmask of valid business days −

cbdOffset = pd.tseries.offsets.CustomBusinessDay(n = 4, weekmask = 'Mon Tue Wed Fri')

Add the offset to the Timestamp and display the Updated Timestamp −

print("\nUpdated Timestamp...\n",timestamp + cbdOffset)

Display the weekmask −

print("\nThe weekmask on the CustomBusinessDay object..\n", cbdOffset.weekmask)

Example

Following is the code −

import pandas as pd

# Set the timestamp object in Pandas
timestamp = pd.Timestamp('2021-10-22 03:10:35')

# Display the Timestamp
print("Timestamp...\n",timestamp)

# Create the CustomBusinessDay Offset
# CustomBusinessDay is the DateOffset subclass representing custom business days excluding holidays
# Weekmask of valid business days
cbdOffset = pd.tseries.offsets.CustomBusinessDay(n = 4, weekmask = 'Mon Tue Wed Fri')

# Display the CustomBusinessDay Offset
print("\nCustomBusinessDay Offset...\n",cbdOffset)

# Add the offset to the Timestamp and display the Updated Timestamp
print("\nUpdated Timestamp...\n",timestamp + cbdOffset)

# Return frequency applied on the given CustomBusinessDay Offset object as a string
print("\nFrequency applied on the given CustomBusinessDay Offset object...\n",cbdOffset.freqstr)

# return the count of increments on the given CustomBusinessDay object
print("\nThe count of increments on the CustomBusinessDay object..\n", cbdOffset.n)

# display the weekmask
print("\nThe weekmask on the CustomBusinessDay object..\n", cbdOffset.weekmask)

Output

This will produce the following code −

Timestamp...
 2021-10-22 03:10:35

CustomBusinessDay Offset...
 <4 * CustomBusinessDays>

Updated Timestamp...
 2021-10-29 03:10:35

Frequency applied on the given CustomBusinessDay Offset object...
 4C

The count of increments on the CustomBusinessDay object..
 4

The weekmask on the CustomBusinessDay object..
 Mon Tue Wed Fri
