Python Pandas - Get the Day of the year from Period object


To get day of the year from Period object, use the period.dayofyear 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("2020-09-23")
period2 = pd.Period(freq="D", year = 2021, month = 7, day = 16, hour = 2, minute = 35)

Display the Period objects −

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

Get the day of the year from two Period objects −

res1 = period1.dayofyear
res2 = period2.dayofyear

Example

Following is the code −

import pandas as pd

# The pandas.Period represents a period of time
# creating two Period objects
period1 = pd.Period("2020-09-23")
period2 = pd.Period(freq="D", year = 2021, month = 7, day = 16, hour = 2, minute = 35)

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

# get the day of the year from two Period objects
res1 = period1.dayofyear
res2 = period2.dayofyear

# Return the day of the year from the two Period objects
# The return value ranges between 1 to 365 for regular years and 1 to 366 for leap years
print("\nDay of the year from the 1st Period object ...\n", res1)
print("\nDay of the year from the 2nd Period object...\n", res2)

Output

This will produce the following code −

Period1...
2020-09-23
Period2...
2021-07-16

Day of the year from the 1st Period object ...
267

Day of the year from the 2nd Period object...
197
