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

Example 2

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

Example 3

Example 3
 1 import pandas as pd
 2 
 3 tstamp1 = pd.Timestamp(2024, 2, 1)
 4 print('The timestamp object :', tstamp1)
 5 
 6 offset1 = pd.tseries.offsets.BQuarterBegin(n = 3, startingMonth = 4, normalize = True)
 7 res1 = offset1.is_quarter_start(tstamp1)
 8 print(f'Does timestamp at start of quarter :{res1}')
In the above example, a Timestamp object is created by passing a date value and BQuarterBegin with normalize as true and startingMonth and unit frequency as 3. A is_quarter_start() function is called by passing a timestamp that determine whether the timestamp occurs at the start of quarter month.
Output
 1 The timestamp object : 2024-02-01 00:00:00
 2 Does timestamp at start of quarter :True
