Common questions
- How does the age calculator work?
- It counts complete years from your birth date, then complete months, then the remaining days, using real calendar dates. Leap years and different month lengths are handled automatically because the math walks the actual calendar instead of assuming 30-day months.
- Why do different sites show a slightly different months-and-days result?
- Month lengths vary from 28 to 31 days, so there is more than one convention for expressing the leftover part of an age. Tools that approximate a month as 30 days can land a day or two away from a calendar-accurate count for the same birth date.
- What does the total-days figure mean?
- It is the exact number of calendar days between your birth date and today, including leap days. It grows by one every day regardless of months or years, which makes it useful for milestones like a 10,000th day.
