- **Formula:**
  ```
  Decimal Hours = Hours + (Minutes / 60) + (Seconds / 3600)
  Industrial Minutes = Decimal Hours × 100
  Total Minutes = (Hours × 60) + Minutes + (Seconds / 60)
  ```
- **Calculation Steps:**

  2. Validate ranges (hours: 0-23, minutes: 0-59, seconds: 0-59)
  3. Calculate decimal hours
  4. Calculate industrial minutes
  5. Calculate total minutes
  6. Format results for display
- **Example:**
  - Input: "8:30"
  - Calculation:
    - Hours: 8, Minutes: 30
    - Decimal Hours: 8 + (30/60) = 8.5
    - Industrial Minutes: 8.5 × 100 = 850
    - Total Minutes: (8 × 60) + 30 = 510
  - Output:
    - Normalzeit: "08:30"
    - Dezimalstunden: "8,50 h"
    - Industrieminuten: "510"
- **Edge Cases:**
  - Single digit input (e.g., "8") → Treated as hours, formatted to "08:00"
  - Two digit input (e.g., "11") → Treated as hours if ≤23, else as HH:MM
  - Three digit input (e.g., "123") → Treated as "01:23"
  - Four digit input (e.g., "1234") → Treated as "12:34"
  - Partial input (e.g., "12:3") → Formatted to "12:30" on blur

- **Formula:**
  ```
  Hours = floor(Decimal Hours)
  Minutes = round((Decimal Hours - Hours) × 60)
  Industrial Minutes = Decimal Hours × 100
  ```
- **Calculation Steps:**
  1. Parse decimal input (handle comma separator)
  2. Validate decimal value
  3. Extract hours (integer part)
  4. Calculate minutes (decimal part × 60, rounded)
  5. Calculate industrial minutes
  6. Format results for display
- **Example:**
  - Input: "8,5"
  - Calculation:
    - Decimal Hours: 8.5
    - Hours: 8
    - Minutes: round((8.5 - 8) × 60) = round(0.5 × 60) = 30
    - Industrial Minutes: 8.5 × 100 = 850
  - Output:
    - Normalzeit: "08:30"
    - Dezimalstunden: "8,50 h"
    - Industrieminuten: "850"
- **Edge Cases:**
  - Comma separator (e.g., "8,5") → Converted to 8.5
  - Leading zero (e.g., "0,5") → Treated as 0.5 hours
  - Whole number (e.g., "8") → Treated as 8.0 hours

    - Default: "08:00"
    - Validation: Valid time format
  - `workEndTime` (time): Work end time
    - Type: Time input (HH:MM)
    - Default: "17:00"
    - Validation: Valid time format, must be after start time
  - `workBreakTime` (text): Break duration in minutes
    - Type: Text input (number)
    - Default: "30"
    - Validation: Positive number
- **Output Fields:**
  - Same as Mode 1 (Normalzeit)
  - Plus compliance information
- **Formula:**
  ```
  Start Minutes = Start Hours × 60 + Start Minutes
  End Minutes = End Hours × 60 + End Minutes
  Total Minutes = End Minutes - Start Minutes - Break Minutes
  Hours = floor(Total Minutes / 60)
  Minutes = Total Minutes % 60
  ```
- **Calculation Steps:**
  1. Parse start time to minutes
  2. Parse end time to minutes
  3. Handle overnight shifts (if end < start and start >= 22:00)
  4. Calculate total minutes (end - start - break)
  5. Convert to hours and minutes
  6. Validate compliance with German labor laws
  7. Format results for display
- **Example:**
  - Input: Start "08:00", End "17:00", Break "30"
  - Calculation:
    - Start Minutes: 8 × 60 + 0 = 480
    - End Minutes: 17 × 60 + 0 = 1020
    - Total Minutes: 1020 - 480 - 30 = 510
    - Hours: floor(510 / 60) = 8
    - Minutes: 510 % 60 = 30
  - Output:
    - Normalzeit: "08:30"
    - Dezimalstunden: "8,50 h"
    - Industrieminuten: "510"
- **Edge Cases:**
  - Overnight shifts: Start 22:00, End 06:00 → Adds 24 hours to end time
  - Zero break: Break "0" → No break deducted
  - Long shifts: Validates against maximum working hours
  - Invalid times: End before start → Error message

### Input Modes

**Single Input Mode:**

- Single calculation at a time
- Real-time calculation as user types

### Constants and Thresholds

**2026 Values:**

- **Conversion Formula:** Stable (no law changes)
  - 1 Hour = 60 Minutes
  - 1 Hour = 100 Industrial Minutes (REFA standard)
  - Decimal Hours = Hours + (Minutes / 60) + (Seconds / 3600)
  - Industrial Minutes = Decimal Hours × 100
- **REFA Methodology:** Standard conversion rates (unchanged)
- **Working Time Limits (ArbZG 2026):**
  - Maximum daily hours: 8 hours standard (can extend to 10 hours if averaged over 6 months/24 weeks)
  - Break requirement: 30 minutes after 6 hours, 45 minutes after 9 hours
  - Rest period: 11 hours between shifts (10 hours in some sectors)
  - Weekly limit: Average 48 hours per week (can reach 60 hours temporarily with averaging)

**Formula Note:**
- Code uses: `Industrial Minutes = Decimal Hours × 100` where `Decimal Hours = Hours + (Minutes / 60)`
- FAQ mentions: `Industrial Minutes = (Hours × 100) + (Minutes × 1.67)`
- Both formulas are mathematically equivalent (small rounding differences). Code formula is more precise.

**Previous Values (for reference):**

- Same as 2026 (formula stable)

### Validation Rules

## Formulas & Calculations

### Primary Formulas

**Normal Time to Decimal Hours:**

```
Decimal Hours = Hours + (Minutes / 60) + (Seconds / 3600)
```

**Decimal Hours to Normal Time:**

```
Hours = floor(Decimal Hours)
Minutes = round((Decimal Hours - Hours) × 60)
Seconds = round((Decimal Hours - Hours - Minutes/60) × 3600)
```

**Decimal Hours to Industrial Minutes:**

```
Industrial Minutes = Decimal Hours × 100
```

**Normal Time to Industrial Minutes:**

```
Industrial Minutes = (Hours × 60 + Minutes + Seconds/60) × (100/60)
Simplified: Industrial Minutes = Decimal Hours × 100
```

**Work Time Calculation:**

```
Start Minutes = Start Hours × 60 + Start Minutes
End Minutes = End Hours × 60 + End Minutes
Total Minutes = End Minutes - Start Minutes - Break Minutes
Hours = floor(Total Minutes / 60)
Minutes = Total Minutes % 60
```

### Legal Basis

- **REFA Methodology:** Standard industrial time tracking methodology
- **Arbeitszeitgesetz (ArbZG):** German Working Time Act
  - Maximum daily hours: 8 hours (with exceptions up to 10 hours)
  - Break requirement: After 6 hours continuous work, minimum 30 minutes break
  - Weekly limit: Average 48 hours per week (EU directive)
- **No specific conversion laws:** Conversion formula is standard methodology, not legal requirement

### Step-by-Step Calculation Example

**Input:** Normal Time "8:30"

1. Parse input:

   - Hours: 8
   - Minutes: 30
   - Seconds: 0 (not specified)

2. Calculate decimal hours:

   - Decimal Hours = 8 + (30 / 60) = 8 + 0.5 = 8.5

3. Calculate industrial minutes:

   - Industrial Minutes = 8.5 × 100 = 850

4. Calculate total minutes:

   - Total Minutes = (8 × 60) + 30 = 480 + 30 = 510

5. Format results:
   - Normalzeit: "08:30"
   - Dezimalstunden: "8,50 h"
   - Industrieminuten: "510"

**Output:**

- Normalzeit: "08:30"
- Dezimalstunden: "8,50 h"
- Industrieminuten: "510"
