Pandas tseries offsets Minute function is_quarter_start() in Python
The Pandas tseries offsets Minute function is_quarter_start() used to determine whether a timestamp occurs on the quarter start. It returns a boolean value that specifies whether a timestamp occurs at the quarter start.
Syntax
 1 Minute.is_quarter_start()
is_quarter_start() function
 1 import pandas as pd
 2 
 3 offset = pd.tseries.offsets.Minute()
 4 
 5 tstamp = pd.Timestamp(2022, 4, 1)
 6 res = offset.is_quarter_start(tstamp)
 7 print(f'Does timestamp occurs at quarter start : {res}')
 8 
 9 tstamp1 = pd.Timestamp(2022, 3, 1)
 10 res1 = offset.is_quarter_start(tstamp1)
 11 print(f'Does timestamp occurs at quarter start : {res1}')
In the above example, a Timestamp objects are created by passing a date value. A is_quarter_start() function is called that determine whether a timestamp occurs at the start of quarter. The result is assign to the variable that will be printed on console.
Output
 1 Does timestamp occurs at quarter start : True
 2 Does timestamp occurs at quarter start : False

Example 2

Example 2
 1 import pandas as pd
 2 
 3 tstamp = pd.Timestamp(2023, 4, 1, 12, 3)
 4 print('The timestamp object :', tstamp)
 5 
 6 offset = pd.tseries.offsets.Minute(n = 1)
 7 res = offset.is_quarter_start(tstamp)
 8 print(f'Does timestamp occurs at quarter start : {res}')
In the above example, a Timestamp objects are created by passing a date value and Minute object with unit frequency as 1. A is_quarter_start() function is called that determine whether a timestamp occurs at the start of quarter.
Output
 1 The timestamp object : 2023-04-01 12:03:00
 2 Does timestamp occurs at quarter start : True

Example 3

Example 3
 1 import pandas as pd
 2 
 3 tstamp1 = pd.Timestamp(2024, 10, 1, 10, 4)
 4 print('The timestamp object :', tstamp1)
 5 
 6 offset1 = pd.tseries.offsets.Minute(n = 3)
 7 res1 = offset1.is_quarter_start(tstamp1)
 8 print(f'Does timestamp occurs at quarter start : {res1}')
In the above example, a Timestamp objects are created by passing a date value and Minute object with unit frequency as 3. A is_quarter_start() function is called that determine whether a timestamp occurs at the start of quarter.
Output
 1 The timestamp object : 2024-10-01 10:04:00
 2 Does timestamp occurs at quarter start : True
