Production Calendar

Production Calendar is one verified set of Russian working-day data for both people and programs. The status of any date, working-time norms and deadline math come with a legal basis: which Labour Code article or government decree applied, and in which calendar version.

This is not a pretty grid. A wrong answer cannot pass unnoticed. Working days and hour norms for 2022–2026 are checked against the official production calendar down to each month. If the data diverge from the reference, the service returns an error and does not answer at all.

Where to open it

• the web service at calendar.legalic.ru — year grid, day card and calculator; it runs locally in the browser, no sign-up;
• the Android app on Google Play — fully offline, 2022–2027 data baked in, personal notes only on the phone;
• REST API, MCP and exports — no keys and no request quota.

Calendar and calculator

• a year grid with statuses: working, shortened, day off, transferred day off, working Saturday, non-working holiday;
• a day card: how the status was derived, a link to the rule, the calendar version, hours for 40 / 36 / 24-hour weeks;
• norms for a week, month, quarter, half-year and year — including a custom week (for example 39 hours for medical staff) by Ministry of Health order No. 588n;
• ±N working days, working days between two dates, the nearest working day;
• the result copies with the original inputs and the data version — a reproducible note, not a bare number.

Android

The app works without a network: the calendar, calculations and personal notes stay on the device. You can add a note and personal overrides (“my day off” / “my working day”) for a custom schedule. The “include my records” switch changes the calculator, and the result is marked. There is no account, no ads and no data collection.

API and automation

The open REST API returns a day’s status, ranges, the next working day, adding working days, counts and hour norms. Responses use ETag caching. A query outside the loaded years returns 422 instead of inventing a day from a weekend rule. Example:

POST https://calendar.legalic.ru/api/v1/calendars/RU-FEDERAL/calc/add-working-days — add working days to a date; the response includes the date, calendar version and a preliminary flag.

For AI assistants there is MCP: claude mcp add --transport http prodcal https://calendar.legalic.ru/mcp. Tools: day status, nearest working day, ±N working days, counts, hour norms, year totals. A full year exports as JSON, CSV or ICS. The TypeScript engine can be embedded and run locally.

Details, live curl examples and the quality rules are on the about page.

Data

The service provides reference data and calculations. It does not replace checking the statutes or professional advice on procedural deadlines and payroll.
