Russian Calendar

API

Check Russian holidays and working days with this open-source calendar API

Overview

The Russian Calendar API offers endpoints to verify if a date is a Russian federal holiday, retrieve annual holiday lists, or confirm working day status. Responses are in JSON format for easy integration. Key endpoints include GET /holidays/{YYYY-MM-DD} (returns holiday details if applicable) and GET /working-day/{YYYY-MM-DD} (boolean result). Use cases: scheduling apps for Russian users, payroll systems calculating working days, event planning tools avoiding holidays, and travel apps adjusting for non-working days in Russia.

script.js JS


fetch('https://github.com/egno/work-calendar')
  .then(res => res.json())
  .then(data => console.log(data))
