A JavaScript library that calculates public, bank, and observance holidays for 206 countries, their states and regions, with timezone awareness and multi-language holiday names. It supports Gregorian, Islamic, Hebrew, and Chinese calendars and can generate custom holiday rules.

Use cases

  • check if a date is a public holiday in a specific country
  • get holidays for a state or region with timezone handling
  • generate holiday calendars for HR and payroll systems
  • localize holiday names in multiple languages
  • build an iCal holiday calendar feed
  • add custom company holidays alongside official ones

When to choose

  • you need worldwide holiday data covering many countries and subdivisions
  • you need timezone-aware holiday start/end times
  • you need multi-language holiday names or custom holiday rules in JavaScript

When to avoid

  • you need exact Islamic holiday dates, which depend on moon sighting
  • you need a hosted holiday API rather than an embeddable library
  • your stack is not JavaScript/Node.js
