# Using MM-DD format
feasts = get_feast_for_date("01-09")

## Data Model

### `Feast` Class

Represents a Catholic feast day with the following attributes:

```python
@dataclass
class Feast:
    date: str          # Date string (e.g., "January 9")
    title: str         # Feast title
    description: str   # Detailed description
    color: str         # Liturgical color (White, Red, etc.)
    type: str          # Type (Solemnity, Memorial, etc.)
    class_: str        # Classification (A, B, C, D, E)
    tags: List[str]    # Associated tags
```

**Methods:**
- `to_dict()`: Convert to dictionary
- `from_dict(data)`: Create from dictionary (class method)

**Example:**
```python
feast = get_feast_for_date("Jan 9")[0]
print(f"Title: {feast.title}")
print(f"Type: {feast.type}")
print(f"Color: {feast.color}")
print(f"Class: {feast.class_}")
print(f"Tags: {', '.join(feast.tags)}")
```

## Advanced Examples

### Search Combinations

```python
from feastdays import search_feasts_by_tag, search_feasts_by_type

# Find all Marian solemnities
marian_feasts = search_feasts_by_tag("mary")
solemnities = search_feasts_by_type("Solemnity")
marian_solemnities = [f for f in marian_feasts if f in solemnities]

# Get all Opus Dei specific celebrations
opus_dei_feasts = search_feasts_by_tag("opus dei")
for feast in opus_dei_feasts:
    print(f"{feast.date}: {feast.title}")
```

### Calendar Statistics

```python
from feastdays import get_feast_count, get_dates_with_feasts, list_all_feasts

# Basic statistics
total_feasts = get_feast_count()
total_dates = len(get_dates_with_feasts())
print(f"Total feasts: {total_feasts}")
print(f"Days with feasts: {total_dates}")

# Feast type distribution
all_feasts = list_all_feasts()
types = {}
for feast in all_feasts:
    feast_type = feast.type or "Unspecified"
    types[feast_type] = types.get(feast_type, 0) + 1

for feast_type, count in sorted(types.items()):
    print(f"{feast_type}: {count}")
```

## Error Handling

The library raises specific exceptions for different error conditions:

```python
from feastdays import get_feast_for_date

try:
    feasts = get_feast_for_date("invalid date")
except ValueError as e:
    print(f"Date parsing error: {e}")

try:
    feasts = get_feast_for_date("Jan 9")
except FileNotFoundError as e:
    print(f"Data file not found: {e}")
except json.JSONDecodeError as e:
    print(f"Invalid JSON data: {e}")
```

## Date Format Reference

| Format Type | Examples |
|-------------|----------|
| Date Objects | `date(2024, 1, 9)`, `datetime.now()` |
| MM-DD | `"01-09"`, `"12-25"` |
| Month Day | `"Jan 9"`, `"January 9"`, `"January 9th"` |
| Day Month | `"9 Jan"`, `"9 January"`, `"9th January"` |
| With Year | `"Jan 9 2024"`, `"9th January 2024"`, `"January 1st 2024"` |

**Note:** The library automatically handles ordinal suffixes (st, nd, rd, th) and is case-insensitive for month names.
