# Weekday Abbreviations

Source: docs/dayjs/customization/weekday-abbreviations.md
Description: 使用Day.js的updateLocale方法配置英文星期缩写，设置为对应的缩写形式。

`Locale#weekdaysShort` 应该是一个缩写的周的数组。

这依赖 [UpdateLocale](/dayjs/plugin/update-locale) 插件，才能正常运行

```javascript
dayjs.extend(updateLocale);

dayjs.updateLocale("en", {
  weekdaysShort: ["Sun", "Mon", "Tue", "Wed", "Thu", "Fri", "Sat"],
});
```
