Age in hours is counted from the date of birth to today — September 10, 2026 here — and not from a rounded number of years. Someone whose 30th birthday is today was born on September 10, 1996 and has lived 10,957 days, which is 262,968 hours. Hours are counted as 24 per day. Local clock changes make two days a year 23 or 25 hours long, so an exact hour count in local time drifts by an hour or two per year; in UTC, 24 hours per day is exact.
