## Code Verification

### Constants Verified

**File: `v2/pages/tools_urlaubsanspruchrechner.php`**

| Constant | Value | Line | Status |
|----------|-------|------|--------|
| `legalBaseDays` | 24 | 832 | ✅ Verified |
| `year` | `new Date().getFullYear()` | 833 | ✅ Dynamic (2026) |
| `isYouth` | false (default) | 836 | ✅ Verified |
| `youthAge` | 16 (default) | 837 | ✅ Verified |
| `isDisabled` | false (default) | 835 | ✅ Verified |

### Formulas Verified

**Daily Calculation:**

```javascript
baseVacationDays = (workDaysPerWeek / 6) * this.legalBaseDays;
// ✅ Verified: Correct formula for 5-day (20) and 6-day (24) weeks
```

**Hourly Calculation:**

```javascript
const legalVacationHours = 144; // 24 days * 6 hours
const baseVacationHours = (weeklyHours / 36) * legalVacationHours;
baseVacationDays = baseVacationHours / dailyHours;
// ✅ Verified: Correct formula for hourly calculation (since 2021)
```

**Pro-rating Formula:**

```javascript
legalVacationDays = (baseVacationDays / 12) * fullMonthsInYear;
// ✅ Verified: Correct pro-rating per BUrlG § 5
```

**Rounding Logic:**

```javascript
finalVacationResult = Math.ceil(finalVacationDays); // Round UP
// ✅ Verified: Correct rounding per BUrlG § 5 Abs. 2
```

**Youth Vacation:**

```javascript
if (youthAge === 15) baseVacationDays = 30;
else if (youthAge === 16) baseVacationDays = 27;
else if (youthAge === 17) baseVacationDays = 25;
// ✅ Verified: Correct values per JArbSchG § 19
```

**Disabled Employee Bonus:**

```javascript
baseVacationDays += 5; // SGB IX: +5 days for disabled employees
// ✅ Verified: Correct bonus per SGB IX § 208
```

### Month Calculation Logic

**15-Day Rule:**

The calculator correctly implements the "15-day rule" for counting full months:

- If start date is after the 15th of the month → doesn't count as full month
- If end date is before the 15th of the month (unless starting on day 1) → doesn't count as full month
- If start and end are in the same month → counts as 1 month if ≥ 15 days, 0 if < 15 days

✅ **Verified:** Logic matches BUrlG requirements
