Python Pandas - Indicate whether the date in DateTimeIndex is the first day of the quarter

PythonServer Side ProgrammingProgramming

To check whether the date in DateTimeIndex is the first day of the quarter, use the DateTimeIndex.is_quarter_start property.

At first, import the required libraries −

import pandas as pd

Create a DatetimeIndex with period 6 and frequency as D i.e. days −

datetimeindex = pd.date_range('2021-10-1 02:30:50', periods=6, tz='Australia/Adelaide', freq='30D')

Display DateTimeIndex −

print("DateTimeIndex...
", datetimeindex)

Check whether the date in DateTimeIndex is the first day of the quarter −

print("
Check whether the date in DateTimeIndex is the first day of the quarter...
",
datetimeindex.is_quarter_start)

Example

Following is the code −

import pandas as pd

# DatetimeIndex with period 6 and frequency as D i.e. days
# The timezone is Australia/Adelaide
datetimeindex = pd.date_range('2021-10-1 02:30:50', periods=6, tz='Australia/Adelaide', freq='30D')

# display DateTimeIndex
print("DateTimeIndex...
", datetimeindex)

# display DateTimeIndex frequency
print("DateTimeIndex frequency...
", datetimeindex.freq)

# Check whether the date in DateTimeIndex is the first day of the quarter
# Result is based on the following quarters of an year:
# Quarter 1 = 1st January to 31st March
# Quarter 2 = 1st April to 30th June
# Quarter 3 = 1st July to 30th September
# Quarter 4 = 1st October to 31st December
print("
Check whether the date in DateTimeIndex is the first day of the quarter...
",
datetimeindex.is_quarter_start)

Output

This will produce the following code −

DateTimeIndex...
DatetimeIndex(['2021-10-01 02:30:50+09:30', '2021-10-31 02:30:50+10:30',
'2021-11-30 02:30:50+10:30', '2021-12-30 02:30:50+10:30',
'2022-01-29 02:30:50+10:30', '2022-02-28 02:30:50+10:30'],
dtype='datetime64[ns, Australia/Adelaide]', freq='30D')
DateTimeIndex frequency...
<30 * Days>

Check whether the date in DateTimeIndex is the first day of the quarter...
