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.
