0How the Age Calculator Works & Frequently Asked Questions
Learn how calendar math calculates your exact age, leap year birthdays, and total milestones.
Exact Calendar Math vs. Average Days
Many basic online tools approximate age by dividing total days by 365.25. This frequently produces inaccurate month and day counts because actual calendar months vary between 28, 29, 30, and 31 days. Utility Seva subtracts dates month-by-month and borrows exact days from the preceding calendar month.
Leap Year & February 29 Birthdays
If you were born on leap day (February 29), in non-leap years your next birthday is celebrated on February 28. In leap years (such as 2024, 2028), your birthday countdown precisely matches February 29.
