Frequently Asked Questions
How accurate is this age calculator?
Our calculator provides exact calculations based on your birth date and the current date. The seconds counter is accurate to the moment you load the page, though it doesn't update in real-time as you view it.
What are the milestone dates?
We calculate upcoming "round number" milestones like your next million-second birthday, next thousand-day birthday, and next hundred-month birthday. These make for fun celebration dates that most people never think about!
Can I share my age calculation with friends?
Yes! Use the "Share on WhatsApp" button to share your age stats, or use "Copy Link" to get a shareable URL with your birthday pre-filled. When friends click your link, they'll see your age calculation and can then enter their own birthday.
Why does knowing my age in different units matter?
It's a fun way to gain perspective on time! Seeing that you've lived millions of seconds or thousands of days can make you appreciate each moment. Plus, it's great for social media posts and conversation starters.
How is this different from the "How Old Will I Be?" calculator?
The "How Old Will I Be?" tool calculates your age at a future date, while this "Age in Different Units" tool shows your current age expressed in multiple time units (seconds, minutes, hours, etc.) and highlights upcoming milestones.
What should I do to never miss a birthday?
Sign up for BirthdayTexts! You'll get automatic SMS reminders the day before each birthday, plus optional weekly summaries of upcoming birthdays. It's free to start and takes just minutes to set up all your important dates.
