How is age calculated exactly?
From birth date to target date, counting complete years, remaining months, and remaining days. Example: born Jan 15, 2000; age on Jan 20, 2025 = 25 years 0 months 5 days.
What about leap year birthdays (Feb 29)?
People born Feb 29 celebrate on Feb 28 in non-leap years. Age increases on their "adjusted" birthday.
Does time of birth matter?
Calendar age calculations ignore time of day. Only dates matter. Someone turns a year older at midnight on their birthday.
