Birthday Reminder Skill

Manage birthdays naturally. Store in data/birthdays.md, query with natural language.

Storage

Birthdays are stored in /home/clawd/clawd/data/birthdays.md:

# Geburtstage

- **Valentina** - 14.02.2000 (wird 26)
- **Max** - 15.03.1990

Natural Language Patterns

Adding Birthdays

When user says things like:

• "Valentina hat am 14. Februar Geburtstag"
• "Füge hinzu: Max, 15.03.1990"
• "X wurde am 10.05.1985 geboren"

Action:

1. Parse name and date
2. Extract year if provided
3. Calculate upcoming age: birthday_year - birth_year
4. Append to /home/clawd/clawd/data/birthdays.md
5. Confirm with age info

Querying Birthdays

When user asks:

• "Wann hat Valentina Geburtstag?"
• "Welche Geburtstage kommen als Nächstes?"
• "Wie alt wird Valentina?"
• "Nächster Geburtstag"

Action:

1. Read /home/clawd/clawd/data/birthdays.md
2. Parse all entries
3. Calculate days until each birthday
4. Sort by upcoming date
5. Show age turning if year is known

Listing All

When user says:

• "Zeige alle Geburtstage"
• "Liste meine Geburtstage"

Action:

1. Read the file
2. Show formatted list with days until each

Date Parsing

Support various formats:

• "14. Februar" → 14.02
• "14.02." → 14.02
• "14.02.2000" → 14.02.2000
• "14.2.2000" → 14.02.2000

Age Calculation

from datetime import datetime

def calculate_turning_age(birth_year, birthday_month, birthday_day):
    today = datetime.now()
    birthday_this_year = today.replace(month=birthday_month, day=birthday_day)
    
    if today.date() <= birthday_this_year.date():
        birthday_year = today.year
    else:
        birthday_year = today.year + 1
    
    return birthday_year - birth_year

Days Until Birthday

def days_until(month, day):
    today = datetime.now()
    birthday = today.replace(month=month, day=day)
    if birthday < today:
        birthday = birthday.replace(year=today.year + 1)
    return (birthday - today).days

Automatic Reminders

For cron/reminders, check birthdays daily and notify if:

• 7 days before
• 1 day before
• On the day

Use the check_reminders() logic from scripts/reminder.py.

File Format

Each line: - **Name** - DD.MM.YYYY (wird X) or - **Name** - DD.MM.

Keep the file sorted by date (month/day) for easier reading.
