Pandas如何创建新的日期列和可变的月份列，并找到紧随其后的季度的第一个工作日？

import pandas as pd
import numpy as np
import datetime as dt

df = pd.DataFrame({'date': pd.date_range(start='2022-01-01', end='2022-12-31')})

df['new_date'] = pd.to_datetime(df['date'])
df['month'] = df['new_date'].dt.month

df['next_quarter'] = df['new_date'] + pd.offsets.QuarterEnd(1)
df['next_quarter_first_workday'] = df['next_quarter'] + pd.offsets.BDay()
