Yes! Use the "Age on Date" tab or change the "Age At Date" in My Age tab to any past or future date to calculate your age at that specific time.

Once you enter your date of birth, the counter calculates total seconds from your birth date to right now and increments every second in real-time using JavaScript's setInterval.
