## New Features

### 1. Automatic Calculations

**Added:** Two new calculation fields after date inputs.

**Abwesenheitstage (B10):**
- **Formula:** `=IF(AND(ISNUMBER(B8),ISNUMBER(B9)),B9-B8+1,0)`
- **Purpose:** Automatically calculates total calendar days of absence
- **Format:** Number format "0"
- **Location:** A10 (label), B10 (formula)
- **Improvement:** Uses `ISNUMBER()` instead of `<>""` for better date validation

**Werktage (B11):**
- **Formula:** `=IFERROR(IF(AND(ISNUMBER(B8),ISNUMBER(B9)),NETWORKDAYS(B8,B9),0),0)`
- **Purpose:** Calculates working days excluding weekends
- **Format:** Number format "0"
- **Location:** A11 (label), B11 (formula)
- **Note:** Uses NETWORKDAYS function (works in Excel and Google Sheets)
- **Improvement:** Wrapped in `IFERROR()` for error handling

**Impact:** Users no longer need to manually calculate absence duration.

### 2. Helper Cells

**Added:** Two helper cells in column C for additional feedback.

**Days Until Absence (C8):**
- **Formula:** `=IFERROR(IF(ISNUMBER(B8),IF(B8-TODAY()>0,"in "&(B8-TODAY())&" Tagen",IF(B8-TODAY()=0,"heute","vor "&ABS(B8-TODAY())&" Tagen")),""),"")`
- **Purpose:** Shows descriptive text about days until/since absence starts
- **Output Examples:**
  - Future dates: "in 99 Tagen" (in 99 days)
  - Today: "heute" (today)
  - Past dates: "vor 5 Tagen" (5 days ago)
  - No date: empty string
- **Preset:** `info_cell`
- **Improvement:** Includes descriptive German text for better user understanding, handles all date scenarios (future, today, past)

**Date Range Validation (C9):**
- **Formula:** `=IF(AND(ISNUMBER(B8),ISNUMBER(B9)),IF(B9>=B8,"OK","Enddatum muss >= Startdatum sein"),"")`
- **Purpose:** Visual feedback for date range validation
- **Preset:** `info_cell`
- **Improvement:** Uses `ISNUMBER()` instead of `<>""` for better date validation

**Impact:** Users get immediate feedback on date validity and timing.

### 3. Enhanced Data Validation

**Added:** Multiple new validation rules for better data quality.

**Email Format Validation (B5):**
- **Type:** Custom formula
- **Formula:** `=OR(ISBLANK(B5),AND(LEN(B5)>0,ISNUMBER(SEARCH("@",B5)),ISNUMBER(SEARCH(".",B5)),LEN(B5)>=5))`
- **Error Message:** "Bitte geben Sie eine gültige E-Mail-Adresse ein (Format: name@domain.de)"
- **Input Message:** "Geben Sie Ihre E-Mail-Adresse ein"
- **Improvement:** Allows blank (optional field), adds minimum length check (5 chars)

**Date Range Validation (B9):**
- **Type:** Custom formula
- **Formula:** `=OR(ISBLANK(B8),ISBLANK(B9),B9>=B8)`
- **Error Message:** "Das Enddatum muss nach dem Startdatum liegen."
- **Input Message:** "Geben Sie ein Enddatum ein, das nach dem Startdatum liegt"
- **Improvement:** Allows validation when either field is blank (prevents premature errors)

**Required Field Validation:**
- **Fields:** B3 (name), B8 (start date), B9 (end date), B12 (reason)
- **Type:** Custom formula
- **Formulas:** 
  - B3: `=LEN(B3)>0` (text field - checks for non-empty string)
  - B8: `=ISNUMBER(B8)` (date field - checks for valid date number)
  - B9: `=ISNUMBER(B9)` (date field - checks for valid date number)
  - B12: `=LEN(B12)>0` (text field - checks for non-empty string)
- **Error Message:** "Dieses Feld ist erforderlich."
- **Input Message:** "Bitte füllen Sie dieses Feld aus"
- **Improvement:** Uses `ISNUMBER()` for date fields (more accurate than `<>""`), `LEN()>0` for text fields

**Substitution Contact Validation:**
- **Fields:** B15 (substitution name), B16 (substitution contact)
- **Type:** Custom formula
- **Formula:** `=OR(ISBLANK(B15),AND(LEN(B15)>0,LEN(B16)>0))`
- **Error Message:** "Wenn eine Vertretung angegeben wird, sollte auch ein Kontakt vorhanden sein."
- **Input Message:** "Geben Sie den Namen und Kontakt der Vertretung ein"
- **Improvement:** Uses `ISBLANK()` instead of `=""` for better empty cell detection

**Impact:** Prevents invalid data entry and improves data quality.

## Dynamic Email Text Formulas (2026-03-08)

**Issue Identified:** Email text cells (B22, B24, B26, B27, B28, B30) were static text, requiring manual updates when input data changed.

**Solution:** Converted all email text cells to dynamic formulas that automatically reference input cells.

### Dynamic Formula Cells

**B22 - Date Range Text:**
- **Formula:** `=IF(AND(ISNUMBER(B8),ISNUMBER(B9)),"vom "&TEXT(B8,"dd.mm.yyyy")&" bis zum "&TEXT(B9,"dd.mm.yyyy"),"")`
- **Purpose:** Automatically generates "vom [start date] bis zum [end date]" text
- **References:** B8 (start date), B9 (end date)
- **Format:** Standard date format (dd.mm.yyyy) - compatible with both Excel and Google Sheets

**B24 - Start Date:**
- **Formula:** `=IF(ISNUMBER(B8),TEXT(B8,"dd.mm.yyyy"),"")`
- **Purpose:** Formats start date for email text
- **References:** B8 (start date)
- **Format:** Standard date format (dd.mm.yyyy) - compatible with both Excel and Google Sheets

**B26 - End Date:**
- **Formula:** `=IF(ISNUMBER(B9),TEXT(B9,"dd.mm.yyyy"),"")`
- **Purpose:** Formats end date for email text
- **References:** B9 (end date)
- **Format:** Standard date format (dd.mm.yyyy) - compatible with both Excel and Google Sheets

**B27 - Absence Reason Text:**
- **Formula:** `=IF(LEN(B12)>0,IF(B12="Urlaub","im Urlaub.",IF(B12="Krankheit","krankheitsbedingt abwesend.",IF(B12="Elternzeit","in Elternzeit.",IF(B12="Fortbildung","auf Fortbildung.",IF(B12="Dienstreise","auf Dienstreise.",IF(B12="Sonderurlaub","im Sonderurlaub.",IF(B12="Unbezahlter Urlaub","im unbezahlten Urlaub.",""))))))),"")`
- **Purpose:** Automatically generates appropriate German text based on absence reason
- **References:** B12 (absence reason dropdown)
- **Mapping:**
  - "Urlaub" → "im Urlaub."
  - "Krankheit" → "krankheitsbedingt abwesend."
  - "Elternzeit" → "in Elternzeit."
  - "Fortbildung" → "auf Fortbildung."
  - "Dienstreise" → "auf Dienstreise."
  - "Sonderurlaub" → "im Sonderurlaub."
  - "Unbezahlter Urlaub" → "im unbezahlten Urlaub."

**B28 - Substitution Contact Text:**
- **Formula:** `=IF(AND(LEN(B15)>0,LEN(B16)>0),"In dringenden Fällen wenden Sie sich bitte an meine Vertretung: "&B15&" ("&B16&").","")`
- **Purpose:** Automatically generates substitution contact text when both name and email are provided
- **References:** B15 (substitution name), B16 (substitution contact)

**B30 - Name Signature:**
- **Formula:** `=IF(LEN(B3)>0,B3,"")`
- **Purpose:** Automatically uses name from personal data section
- **References:** B3 (name)

### Impact

- **Eliminates Manual Updates:** Users no longer need to manually copy dates, names, and reasons into email text
- **Prevents Errors:** Automatic updates ensure email text always matches input data
- **Improves User Experience:** Template becomes truly automated - fill inputs, email text generates automatically
- **Maintains Flexibility:** Users can still manually edit formulas if needed for custom text

### Example Rows Updated

Removed static values for B22, B24, B26, B27, B28 from `example_rows` since these cells now calculate automatically from input data.

## Formula Improvements (2026-03-08)

### Best Practices Applied

**1. Error Handling:**
- Added `IFERROR()` wrapper to NETWORKDAYS formula (B11) to prevent errors
- Added `IFERROR()` wrapper to TODAY() calculation (C8) for robustness

**2. Date Validation:**
- Replaced `<>""` checks with `ISNUMBER()` for date fields (B8, B9)
- More accurate validation for date cells (distinguishes empty from invalid)

**3. Text Validation:**
- Used `LEN()>0` for text fields instead of `<>""`
- More explicit and readable validation logic

**4. Empty Cell Detection:**
- Used `ISBLANK()` for date fields in conditional formatting
- Used `LEN()=0` for text fields in conditional formatting
- More accurate than `=""` checks

**5. Data Validation Improvements:**
- Email validation: Added minimum length check (5 chars) and allows blank
- Date range validation: Allows validation when either field is blank
- Substitution validation: Uses `ISBLANK()` for better empty detection

**Impact:** Formulas are more robust, handle edge cases better, and follow Excel best practices.
