Exchange_calendars 是一个用于查询证券交易日历的 Python 库。开箱即用，内含世界50+个交易所的交易日历，包括中国市场和港股市场，非常方便。
同时，如果你找到了Exchange_calendars 上没有的市场的交易日历，可以向他们提交PR，创建一个新的交易所日历。
注意，本模块最低支持的Python版本为3.8.
1.准备
开始之前，你要确保Python和pip已经成功安装在电脑上，如果没有，请访问这篇文章：超详细Python安装指南 进行安装。
(可选1) 如果你用Python的目的是数据分析，可以直接安装Anaconda：Python数据分析与挖掘好帮手—Anaconda，它内置了Python和pip.
(可选2) 此外，推荐大家用VSCode编辑器来编写小型Python项目：Python 编程的最好搭档—VSCode 详细指南
Windows环境下打开Cmd(开始—运行—CMD)，苹果系统环境下请打开Terminal(command+空格输入Terminal)，输入命令安装依赖：
pip install exchange_calendars
2.Exchange_calendars 基本使用
获取可用日历的列表：
import exchange_calendars as xcals print(xcals.get_calendar_names(include_aliases=False))
结果如下：
['24/5', '24/7', 'AIXK', 'ASEX', 'BVMF', 'CMES', 'IEPA', 'XAMS', 'XASX', 'XBKK', 'XBOG', 'XBOM', 'XBRU', 'XBSE', 'XBUD', 'XBUE', 'XCBF', 'XCSE', 'XDUB', 'XETR', 'XFRA', 'XHEL', 'XHKG', 'XICE', 'XIDX', 'XIST', 'XJSE', 'XKAR', 'XKLS', 'XKRX', 'XLIM', 'XLIS', 'XLON', 'XMAD', 'XMEX', 'XMIL', 'XMOS', 'XNYS', 'XNZE', 'XOSL', 'XPAR', 'XPHS', 'XPRA', 'XSES', 'XSGO', 'XSHG', 'XSTO', 'XSWX', 'XTAE', 'XTAI', 'XTKS', 'XTSE', 'XWAR', 'XWBO', 'us_futures']
其中，XSHG就是中国的沪市、XHKG就是港股。
获取沪市日历：
import exchange_calendars as xcals
xshg = xcals.get_calendar("XSHG")查询某个区间日程是否有开盘：
import exchange_calendars as xcals
xshg = xcals.get_calendar("XSHG")
print(xshg.schedule.loc["2021-12-29":"2022-08-12"])open break_start break_end close 2021-12-29 2021-12-29 01:30:00+00:00 2021-12-29 03:30:00+00:00 2021-12-29 05:00:00+00:00 2021-12-29 07:00:00+00:00 2021-12-30 2021-12-30 01:30:00+00:00 2021-12-30 03:30:00+00:00 2021-12-30 05:00:00+00:00 2021-12-30 07:00:00+00:00 2021-12-31 2021-12-31 01:30:00+00:00 2021-12-31 03:30:00+00:00 2021-12-31 05:00:00+00:00 2021-12-31 07:00:00+00:00 2022-01-04 2022-01-04 01:30:00+00:00 2022-01-04 03:30:00+00:00 2022-01-04 05:00:00+00:00 2022-01-04 07:00:00+00:00 2022-01-05 2022-01-05 01:30:00+00:00 2022-01-05 03:30:00+00:00 2022-01-05 05:00:00+00:00 2022-01-05 07:00:00+00:00 ... ... ... ... ... 2022-08-08 2022-08-08 01:30:00+00:00 2022-08-08 03:30:00+00:00 2022-08-08 05:00:00+00:00 2022-08-08 07:00:00+00:00 2022-08-09 2022-08-09 01:30:00+00:00 2022-08-09 03:30:00+00:00 2022-08-09 05:00:00+00:00 2022-08-09 07:00:00+00:00 2022-08-10 2022-08-10 01:30:00+00:00 2022-08-10 03:30:00+00:00 2022-08-10 05:00:00+00:00 2022-08-10 07:00:00+00:00 2022-08-11 2022-08-11 01:30:00+00:00 2022-08-11 03:30:00+00:00 2022-08-11 05:00:00+00:00 2022-08-11 07:00:00+00:00 2022-08-12 2022-08-12 01:30:00+00:00 2022-08-12 03:30:00+00:00 2022-08-12 05:00:00+00:00 2022-08-12 07:00:00+00:00 [151 rows x 4 columns]
可见，他直接返回了这个区间中所有开盘的日期作为index，并附带了开盘和收盘的UTC时间（需要+8）。
如果你只需要开市的日期，可以这样：
# 公众号：二七阿尔量化
import exchange_calendars as xcals
xshg = xcals.get_calendar("XSHG")
xshg_range = xshg.schedule.loc["2021-12-29":"2022-08-12"]
print(xshg_range.index.strftime("%Y-%m-%d").tolist())效果如下：
['2021-12-29', '2021-12-30', '2021-12-31', '2022-01-04', '2022-01-05', '2022-01-06', '2022-01-07', '2022-01-10', '2022-01-11', '2022-01-12', '2022-01-13', '2022-01-14', '2022-01-17', '2022-01-18', '2022-01-19', '2022-01-20', '2022-01-21', '2022-01-24', '2022-01-25', '2022-01-26', '2022-01-27', '2022-01-28', '2022-02-07', '2022-02-08', '2022-02-09', '2022-02-10', '2022-02-11', '2022-02-14', '2022-02-15', '2022-02-16', '2022-02-17', '2022-02-18', '2022-02-21', '2022-02-22', '2022-02-23', '2022-02-24', '2022-02-25', '2022-02-28', '2022-03-01', '2022-03-02', '2022-03-03', '2022-03-04', '2022-03-07', '2022-03-08', '2022-03-09', '2022-03-10', '2022-03-11', '2022-03-14', '2022-03-15', '2022-03-16', '2022-03-17', '2022-03-18', '2022-03-21', '2022-03-22', '2022-03-23', '2022-03-24', '2022-03-25', '2022-03-28', '2022-03-29', '2022-03-30', '2022-03-31', '2022-04-01', '2022-04-06', '2022-04-07', '2022-04-08', '2022-04-11', '2022-04-12', '2022-04-13', '2022-04-14', '2022-04-15', '2022-04-18', '2022-04-19', '2022-04-20', '2022-04-21', '2022-04-22', '2022-04-25', '2022-04-26', '2022-04-27', '2022-04-28', '2022-04-29', '2022-05-05', '2022-05-06', '2022-05-09', '2022-05-10', '2022-05-11', '2022-05-12', '2022-05-13', '2022-05-16', '2022-05-17', '2022-05-18', '2022-05-19', '2022-05-20', '2022-05-23', '2022-05-24', '2022-05-25', '2022-05-26', '2022-05-27', '2022-05-30', '2022-05-31', '2022-06-01', '2022-06-02', '2022-06-06', '2022-06-07', '2022-06-08', '2022-06-09', '2022-06-10', '2022-06-13', '2022-06-14', '2022-06-15', '2022-06-16', '2022-06-17', '2022-06-20', '2022-06-21', '2022-06-22', '2022-06-23', '2022-06-24', '2022-06-27', '2022-06-28', '2022-06-29', '2022-06-30', '2022-07-01', '2022-07-04', '2022-07-05', '2022-07-06', '2022-07-07', '2022-07-08', '2022-07-11', '2022-07-12', '2022-07-13', '2022-07-14', '2022-07-15', '2022-07-18', '2022-07-19', '2022-07-20', '2022-07-21', '2022-07-22', '2022-07-25', '2022-07-26', '2022-07-27', '2022-07-28', '2022-07-29', '2022-08-01', '2022-08-02', '2022-08-03', '2022-08-04', '2022-08-05', '2022-08-08', '2022-08-09', '2022-08-10', '2022-08-11', '2022-08-12']
