Write a Pandas program to find the all the business quarterly begin and end dates of a specified year.

Sample Solution:

Python Code :

``````import pandas as pd
q_start_dates = pd.date_range('2020-01-01', '2020-12-31', freq='BQS-JUN')
q_end_dates = pd.date_range('2020-01-01', '2020-12-31', freq='BQ-JUN')
print("All the business quarterly begin dates of 2020:")
print(q_start_dates.values)
print("\nAll the business quarterly end dates of 2020:")
print(q_end_dates.values)
``````

Sample Output:

```All the business quarterly begin dates of 2020:
['2020-03-02T00:00:00.000000000' '2020-06-01T00:00:00.000000000'
'2020-09-01T00:00:00.000000000' '2020-12-01T00:00:00.000000000']

All the business quarterly end dates of 2020:
['2020-03-31T00:00:00.000000000' '2020-06-30T00:00:00.000000000'
