## Implementation Status

### ✅ Completed Updates

1. **ShiftOps Fallback Holidays** - Updated to 2026 dates
2. **Excel Template Generator** - Added 2026 dataset

## Implementation Notes

### ShiftOps Fallback Update

The fallback function uses `$currentYear = date('Y')` but the holiday arrays are hardcoded with 2025 dates. Options:

1. **Simple Update:** Replace all 2025 dates with 2026 dates
2. **Multi-year Fallback:** Include both 2025 and 2026 data, select based on `$currentYear`
3. **Dynamic Generation:** Calculate Easter-based holidays dynamically

**Recommended:** Option 1 (simple update) for now, with note to update annually.

### Excel Template Generator Update

Options:

1. **Add 2026 Dataset:** Add `german_holidays_2026` alongside existing 2025 dataset
2. **Replace Dataset:** Replace 2025 with 2026
3. **Keep Both:** Maintain both for backward compatibility

**Recommended:** Option 1 (add 2026 dataset) to maintain backward compatibility.

## Next Steps

✅ **All updates completed!**

### Annual Maintenance

Both areas should be updated annually:

1. **ShiftOps Fallback Holidays** - Update `getFallbackHolidays()` function with new year dates
2. **Excel Template Generator** - Add new year dataset to `public-data.json`

**Update Schedule:** January of each year (after holiday dates are confirmed)
