How to check if the date is the quarter's first day in Pandas

Onyejiaku Theophilus Chidalu

Overview

The .is_quarter_start attribute of the Pandas.Timestamp object, which is an equivalent of Python's datetime object, is used to check if the date is the first day of the quarter or not.

Syntax

The .is_quarter_start attribute takes the following syntax:

Timestamp.is_quarter_start
Syntax for the .is_quarter_start attribute in Pandas

Parameter value

Since .is_quarter_start is an attribute, it takes no parameter value.

Return value

The .is_quarter_start attribute returns a Boolean value indicating if the date is the last day of the quarter (True) or not (False).

Example

# A code to illustrate the .is_quarter_end attribute in Pandas
# importing the pandas library
import pandas as pd

# creating a Timestamp object
a = pd.Timestamp(2022, 4, 30)
b = pd.Timestamp(2022, 4, 1)

# checking if date is the first day of the quarter
print(a.is_quarter_start)
print(b.is_quarter_start)
Implementing the .is_quarter_start attribute

Explanation

  • Line 3: We import the pandas library.
  • Lines 6–7: We create Timestamp objects, a and b, representing the month of June.
  • Line 10: We obtain the result indicating whether any of the dates are the first day of the quarter or not, using the .is_quarter_start.
