Exact age calculation requires careful handling of calendar irregularities: months have 28–31 days, and a leap year adds a day every 4 years (with exceptions for century years not divisible by 400).
The years count completed birthday anniversaries. The remaining months count full calendar months after the last birthday. The remaining days cover the final partial month.
Total days is the precise count since birth, accurate to the calendar date. Total hours is days × 24 and does not account for the time of birth within the day.
Exact age is the difference between today and your birth date, carefully accounting for varying month lengths and leap years. Years count completed birthday anniversaries. Remaining months count completed calendar months after the last birthday. Remaining days count the final partial month.
