使用自定义日历

以下是如何使用自定义日历。

获取两个日期之间的假期

import pandas as pd
from datetime import date

# Creating some boundaries
year = 2016
start = date(year, 1, 1)
end = start + pd.offsets.MonthEnd(12)

# Creating a custom calendar
cal = FrBusinessCalendar()
# Getting the holidays (off-days) between two dates
cal.holidays(start=start, end=end)

# DatetimeIndex(['2016-01-01', '2016-03-28', '2016-05-01', '2016-05-05',
#                '2016-05-08', '2016-07-14', '2016-08-15', '2016-11-01',
#                '2016-11-11', '2016-12-25'],
#               dtype='datetime64[ns]', freq=None)

计算两个日期之间的工作日数

无论将来或过去哪一年，每月都可以获得工作日数。以下是使用自定义日历的方法。

from pandas.tseries.offsets import CDay

# Creating a series of dates between the boundaries 
# by using the custom calendar
se = pd.bdate_range(start=start, 
                    end=end,
                    freq=CDay(calendar=cal)).to_series()
# Counting the number of working days by month
se.groupby(se.dt.month).count().head()

# 1    20
# 2    21
# 3    22
# 4    21
# 5    21
