Add Russia Working Days

Adds or subtracts Russia authority-scope working days in exact coverage.

When to use

You need a deterministic Russia working-day offset.

Do not use when: This package covers the federal statutory/public-holiday layer and the Government-published 2026 transfer days over a Saturday-Sunday baseline. Regional holidays, republic/local holidays, employer, bank, school, shift, sector and collective-agreement schedules are not inferred. Future annual transfer resolutions require a refreshed package.

FAQ

Does this cover every Russian region and employer?

No. It is the federal statutory and Government transfer-day layer; regional, employer, bank, school, shift and sector calendars can differ.

Why is 9 January a day off?

Government Resolution No. 1466 transfers the Saturday 3 January 2026 day off to Friday 9 January.

Are future years included?

No. The package pins 2026 only; future transfer resolutions require refreshed official evidence.
