Holiday object

getHolidays() as well as a matching isHoliday() call return either a list or a single holiday object which consists of:

• {String} date - ISO Date String of (start)-date in local format
• {Date} start - start date of holiday
• {Date} end - end date of holiday
• {String} name - name of holiday using language (if available)
• {String} type - type of holiday public|bank|school|optional|observance
• {Boolean} substitute - (optional) if true holiday substitutes another holiday`
• {String} note - (optional) note`

Dates

The date String represents the start date of the holiday in ISO format without timezone. This string it intended for information only.

start and end are the start/end date of the holiday within the selected timezone of the country, state, region.

Name

The name names the holiday in the local language of the selected country, state, region. The applied language(s) can be requested using getLanguages().

The language can be changed using the setLanguages() method. In case that not translation is available a fall-back to the next given language will be made. E.g. local language is "fr", setLanguages('nl') was called. For all holidays where no dutch translation is available the French version will be used instead.

All holiday names should support an English translation.

Types of holidays

Currently the following type with their meaning are supported

type	meaning
public	public holiday
bank	bank holiday, banks and offices are closed
school	school holiday, schools are closed
optional	majority of people take a day off
observance	optional festivity, no paid day off

Additionally a note field is sometimes available for further clarification.

API

See Holidays API for further information.

Data

All data for the holidays of the different countries is contained in ./data/holidays.json. For changing holiday data edit the appropriate country in ./data/countries. Any details on structure and available grammar for holiday attribution is described in holidays.yaml specification.

Custom builds of holidays.json

If only selected countries are required in data/holidays.json you can add the following script to your npm scripts section. E.g. for picking just US, Canada, Mexico do the following:

"scripts": {
  "build": "holidays2json --pick US,CA,MX --min"
},

The --min switch removes dependencies which are not required for the countries selected. You may not be able to use the full set of rules in case you want to add custom rules.

Alternatively you may use the --omit option.

Manually use

./scripts/holidays2json --pick US,CA,MX

NOTE: There are some countries which depend on data of others which might render the file useless. e.g. "GU" requires "US", so try to pick or omit both.

Bundling with webpack

To minimize bundle sizes consider adding the following lines in your webpack config. Please take a look at ./webpack.config.js. To further reduce size consider custom builds by only selecting required countries.

...
  plugins: [
    new webpack.IgnorePlugin({
      checkResource (resource, context) {
        // ---- do not bundle astronomia vsop planet data
        if (/\/astronomia\/data$/.test(context)) {
          return !['./deltat.js', './vsop87Bearth.js'].includes(resource)
        }
        // ---- do not bundle moment locales
        if (/\/moment\/locale$/.test(context)) {
          return true
        }
        return false
      }
    })

This project also runs in all modern browsers. See ./examples/browser
