5. Frequently Asked Questions (FAQ)

Q1: What if my birthday is in a month with 31 days?
A: This calculator works by month only. For exact date calculations, you would need to consider the specific birth date.

Q2: Do half birthdays have any official significance?
A: No, they're primarily for fun, though some institutions use them for age cutoff determinations.

Q3: How accurate is this calculation?
A: It's mathematically precise for month calculation, but doesn't account for varying month lengths.

Q4: Can I calculate half birthdays for leap year birthdays?
A: Yes, this calculation works the same way regardless of leap years.

Q5: Why add 6 months instead of dividing by 2?
A: Because months cycle every 12 months, adding 6 gives the true halfway point in the yearly cycle.
