Python Pandas - Get day of the month that a Period falls on

To get day of the month that a Period falls on, use the period.day 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)

Get the day of the month from two Period objects −

res1 = period1.day
res2 = period2.day

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 the month from two Period objects
res1 = period1.day
res2 = period2.day

# Return the day of the month from the two Period objects
print("\nDay of the month from the 1st Period object ...\n", res1)
print("\nDay of the month from the 2nd Period object...\n", res2)

Output

This will produce the following code −

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

Day of the month from the 1st Period object ...
18

Day of the month from the 2nd Period object...
22
