Summen- Produkttage?

2040 (und ab dann recht regelmäßig alle 1-3 Jahre)

Python Script:

from datetime import date, datetime, timedelta

def count_special_days(year):
    sum_days = 0
    prod_days = 0
    first_day = datetime(year, 1, 1)
    days_in_year = (datetime(year+1, 1, 1) - first_day).days
    year_short = year % 100
    for day in (first_day + timedelta(day_of_year) for day_of_year in range(days_in_year)):
        if day.day + day.month == year_short:
            sum_days += 1
        if day.day * day.month == year_short:
            prod_days +=1
    return (sum_days, prod_days)
    
for year in range(2024,2050):
    d = count_special_days(year)
    if d[1] > d[0]:
        print(year)
