Formula Used

Let Tb be the birth moment in UTC and Tn the comparison moment in UTC (now if blank). Age in minutes is:

age_minutes = floor((Tn - Tb) / 60,000)
  • Conversion uses exact epoch milliseconds, so leap years, leap days, and daylight transitions are inherently handled.
  • When you select a local time, the value is converted to UTC before subtraction.
