Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Readme

@pangshq/trading_days

判断某一天是否为 A 股交易日。

基于 chinese-days 的中国节假日、调休数据,自动处理周末、法定节假日和调休补班。

安装

npm install @pangshq/trading_days

使用

import { isTradingDay, getTradingDayDetail } from '@pangshq/trading_days';

// 判断今天是否为交易日
isTradingDay(); // true | false

// 判断指定日期
isTradingDay('2025-10-01'); // false(国庆节)
isTradingDay('2025-05-12'); // true(周一)
isTradingDay('2025-05-10'); // false(周六)

// 支持多种日期类型
isTradingDay(new Date('2025-10-01'));       // Date 对象
isTradingDay(new Date('2025-10-01').getTime()); // 时间戳

// 获取日期详情
getTradingDayDetail('2025-10-01');
// { trading: false, name: 'National Day,国庆节,3', date: '2025-10-01' }

getTradingDayDetail('2025-05-12');
// { trading: true, name: 'Monday', date: '2025-05-12' }

API

isTradingDay(date?)

判断指定日期是否为 A 股交易日。

| 参数 | 类型 | 默认值 | 说明 | |------|------|--------|------| | date | Date \| string \| number | new Date() | 日期,支持 Date 对象、ISO 字符串、时间戳 |

返回 boolean

getTradingDayDetail(date?)

获取指定日期的详情。

| 参数 | 类型 | 默认值 | 说明 | |------|------|--------|------| | date | Date \| string \| number | new Date() | 日期,支持 Date 对象、ISO 字符串、时间戳 |

返回 { trading: boolean, name: string, date: string }

判断逻辑

  1. 如果是周末(周六/周日),直接返回 false
  2. 否则,查询 chinese-days 的中国节假日和调休数据:
    • 法定节假日 → 非交易日
    • 调休补班日 → 非交易日
    • 普通工作日 → 交易日
