How the Russia ежегодный отпуск calculator is verified
Inputs
| Input | Field | Type |
|---|---|---|
| Working days in your week | daysPerWeek | number |
| Working days already taken | daysTaken | number |
| Working person with a disability | disabledWorker | boolean |
The formula
Each derived value below is computed by the Valem engine from the expression shown, in this order. Nothing else runs — there is no hidden code path.
| Derived value | Field | Formula (JSONata) |
|---|---|---|
| Calendar Days Entitled | calendarDaysEntitled | disabledWorker ? $const.disabledCalendarDays : $const.statutoryCalendarDays |
| Days Entitled | daysEntitled | $round(calendarDaysEntitled / $const.daysPerCalendarWeek * $n(daysPerWeek), 1) |
| Days Remaining | daysRemaining | ($r := daysEntitled - $n(daysTaken); $r < 0 ? 0 : $round($r, 1)) |
Rates and thresholds
The expressions above read these as $const. They are the figures the annual refresh replaces, so they live as data rather than being written into the formulas — which is what makes a year-on-year change a one-line diff instead of an edit to arithmetic.
| Constant | Value |
|---|---|
statutoryCalendarDays | 28 |
disabledCalendarDays | 30 |
daysPerCalendarWeek | 7 |
Test vectors (4)
Every case is executed against this model on each build, by the Java engine and independently by a JavaScript one. A mismatch of a single cent fails the build, so the page cannot ship advertising a figure the model no longer produces.
Case 1 — R1 28 calendar days on a five-day week is 20 working days
given daysPerWeek | 5 |
|---|---|
given disabledWorker | no |
given daysTaken | 0 |
expect calendarDaysEntitled | 28 |
expect daysEntitled | 20 |
Case 2 — R2 a six-day week gets 24 working days from the same 28
given daysPerWeek | 6 |
|---|---|
given disabledWorker | no |
given daysTaken | 0 |
expect daysEntitled | 24 |
Case 3 — R3 a working person with a disability: 30 calendar days
given daysPerWeek | 5 |
|---|---|
given disabledWorker | yes |
given daysTaken | 0 |
expect calendarDaysEntitled | 30 |
expect daysEntitled | 21.4 |
Case 4 — R4 days taken never push the remainder negative
given daysPerWeek | 5 |
|---|---|
given disabledWorker | no |
given daysTaken | 40 |
expect daysRemaining | 0 |
