Problem
Age_Calculator/Age_Calculator.py computes remaining_months and remaining_days with formulas that produce values >= 12 months and ignore month-length, giving nonsensical output.
Steps
cd Age_Calculator
python3 Age_Calculator.py
# Enter: 2000, 1, 15
Expected
Age: 26 years, 5 months, 19 days
Actual
Age: 26 years, 18 months, and 11 days
Bug at Age_Calculator/Age_Calculator.py:13-14:
remaining_months = abs((12-birthday.month)+today.month)
remaining_days = abs(today.day - birthday.day)
Formula adds instead of taking the wraparound modulo 12, and abs() on day-diff hides negative rollover instead of borrowing from months.
Environment
- OS: Ubuntu 22.04
- Python: 3.10.12
