Age in seconds is counted from the date of birth to today — October 24, 2026 here — and not from a rounded number of years. Someone whose 30th birthday is today was born on October 24, 1996 and has lived 10,957 days, which is 946,684,800 seconds. Seconds are counted as 86,400 per day, which is the calendar definition. One billion seconds is about 31 years and 8 months, so most adults pass that milestone in their early thirties.
