pInstallation Guide

API

It's easy to use Day.js APIs to parse, validate, manipulate, and display dates and times.

dayjs('2018-08-08') // parse

dayjs().format('{YYYY} MM-DDTHH:mm:ss SSS [Z] A') // display

dayjs().set('month', 3).month() // get & set

dayjs().add(1, 'year') // manipulate

dayjs().isBefore(dayjs()) // query

pAPI Reference

I18n

Day.js has great support for internationalization.

But none of them will be included in your build unless you use it.

import 'dayjs/locale/es' // load on demand

dayjs.locale('es') // use Spanish locale globally

dayjs('2018-05-05').locale('zh-cn').format() // use Chinese Simplified locale in a specific instance

pInternationalization

Plugin

A plugin is an independent module that can be added to Day.js to extend functionality or add new features.

import advancedFormat from 'dayjs/plugin/advancedFormat' // load on demand

dayjs.extend(advancedFormat) // use plugin

dayjs().format('Q Do k kk X x') // more available formats
