Non-Working Days (isdayoff.ru) is a production-calendar service that says whether a given date is a working day. Callers can check a single date, request a whole month or year as a compact string of day flags, and choose the country — Russia, other CIS states, the USA and more — with options to treat pre-holiday short days and covid non-working days distinctly. It suits SLA calculations, payroll and business-day date arithmetic. No credentials required. No account needed[isdayoff.ru](https://isdayoff.ru/) **5** actions What the catalog holds today.
