spacetime-holiday v0.3.0

Some holidays are the same day every year, some holidays change astronomically, some by calendar rules like 'third thursday in June'.

This library tries its best to reconcile them.

if it finds a date, it returns a spacetime object.

to conserve filesize of your build, spacetime is a peerDependency, so must be installed separately:

npm i spacetime

npm i spacetime-holiday

const spacetimeHoliday = require('spacetime-holiday')

let s = spacetimeHoliday('easter monday', 2020)
s.format('iso-short')
// 2020-04-12

spacetimeHoliday('groundhog day').format('day') // defaults to next instance
// 'Saturday'

spacetimeHoliday('fall equinox', 2030).format('nice-year')
// 'Sept 22nd, 2030'

// add a timezone
let s = spacetimeHoliday('ramadan', 2019, 'Canada/Pacific')
s.iso()
// 2019-05-05T00:00:00.000-07:00
