modbender Birthday Reminder Skill
Manage birthdays naturally. Store in data/birthdays.md, query with natural language.

- **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:
- Parse name and date
- Extract year if provided
- Calculate upcoming age:
birthday_year - birth_year - Append to
/home/clawd/clawd/data/birthdays.md - 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:
- Read
/home/clawd/clawd/data/birthdays.md - Parse all entries
- Calculate days until each birthday
- Sort by upcoming date
- Show age turning if year is known
Listing All
When user says:
- "Zeige alle Geburtstage"
- "Liste meine Geburtstage"
Action:
- Read the file
- 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.
