Python Pandas - Get the Day of the week the period lies in

To get day of the week that a Period falls on, use the period.dayofweek property

At first, import the required libraries −

import pandas as pd

The pandas.Period represents a period of time. Creating two Period objects −

period1 = pd.Period("2021-09-18")
period2 = pd.Period(freq ='D', year = 2021, month = 9, day = 22, hour = 4, minute = 55)

Display the Period objects −

print("Period1...\n", period1)
print("Period2...\n", period2)

Get the day of week from two Period objects −

res1 = period1.dayofweek
res2 = period2.dayofweek

Example

Following is the code −

import pandas as pd

# The pandas.Period represents a period of time
# creating two Period objects
period1 = pd.Period("2021-09-18")
period2 = pd.Period(freq ='D', year = 2021, month = 9, day = 22, hour = 4, minute = 55)

# display the Period objects
print("Period1...\n", period1)
print("Period2...\n", period2)

# get the day of week from two Period objects
res1 = period1.dayofweek
res2 = period2.dayofweek

# Return the day of the week from the two Period objects
# Results shows Monday=0, Tuesday=1, ... ,Sunday=6
print("\nDay of the week from the 1st Period object ...\n", res1)
print("\nDay of the week from the 2nd Period object...\n", res2)

Output

This will produce the following code −

Period1...
2021-09-18
Period2...
2021-09-22
