How the Estonia põhipuhkus calculator is verified

Inputs

Input	Field	Type
Calendar days of the year you were employed	`calendarDaysWorked`	number
Calendar days in the year	`daysInYear`	number
You are a minor, or have partial or no capacity for work	`extendedEntitlement`	boolean
Calendar days already taken	`daysTaken`	number

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)
Base Days	`baseDays`	`(extendedEntitlement = true ? $const.baseDaysExtended : $const.baseDaysStandard)`
Days Entitled	`daysEntitled`	`($dw := $clampFloorCap($n(calendarDaysWorked), 0, $n(daysInYear)); $round(baseDays / $n(daysInYear) * $dw, 2))`
Days Remaining	`daysRemaining`	`($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
`baseDaysStandard`	28
`baseDaysExtended`	35

Test vectors (9)

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 — N1 a full year is 28 calendar days

given `calendarDaysWorked`	365
given `daysInYear`	365
given `extendedEntitlement`	no
given `daysTaken`	0
expect `baseDays`	28
expect `daysEntitled`	28

Case 2 — A1 the authority's own example, first half: 28 ÷ 365 × 181 (it prints ~13,89; the stated arithmetic gives 13,8849, so 13,88 at two decimals)

given `calendarDaysWorked`	181
given `daysInYear`	365
given `extendedEntitlement`	no
given `daysTaken`	0
expect `daysEntitled`	13.88

Case 3 — A2 the authority's own example, second half: 35 ÷ 365 × 184 = 17,64 exactly as printed

given `calendarDaysWorked`	184
given `daysInYear`	365
given `extendedEntitlement`	yes
given `daysTaken`	0
expect `daysEntitled`	17.64

Case 4 — N2 the extended entitlement over a full year is 35

given `calendarDaysWorked`	365
given `daysInYear`	365
given `extendedEntitlement`	yes
given `daysTaken`	0
expect `baseDays`	35
expect `daysEntitled`	35

Case 5 — N3 half a year is half the entitlement

given `calendarDaysWorked`	182.5
given `daysInYear`	365
given `extendedEntitlement`	no
given `daysTaken`	0
expect `daysEntitled`	14

Case 6 — N4 a leap year divides by 366

given `calendarDaysWorked`	366
given `daysInYear`	366
given `extendedEntitlement`	no
given `daysTaken`	0
expect `daysEntitled`	28

Case 7 — N5 no days employed earns nothing

given `calendarDaysWorked`	0
given `daysInYear`	365
given `extendedEntitlement`	no
given `daysTaken`	0
expect `daysEntitled`	0

Case 8 — N6 days already taken come off the remainder

given `calendarDaysWorked`	365
given `daysInYear`	365
given `extendedEntitlement`	no
given `daysTaken`	10
expect `daysRemaining`	18

Case 9 — N7 taking more than the entitlement never goes negative

given `calendarDaysWorked`	365
given `daysInYear`	365
given `extendedEntitlement`	no
given `daysTaken`	40
expect `daysRemaining`	0
