How would I calculate age in minutes from minute,day,year

E.g.

How would you calculate age of a person in minutes if:

person was born
minute 1, day 2,year 2002

and now it is:
minute 4,day 200,year 2004

Here's one that I did counting days -- could probably be adapted to also include hours/minutes.

A program like Microsoft Excel first converts everything to a single number, usually offset from a known starting date in the 70's or something, and then you convert back to a date.

This Wiki article on Julian days has info on representing any given date in the number of days since January 1, 4713BC. From there, knowing a person's birth date and today's date you can easily get the number of days passed, and hence the number of minutes.

Something like this, I suppose :

SuperStrict

Framework BaH.DateTime
Import BRL.StandardIO

' a start time
Local startTime:TTime = TTime.Create(TDate.Create(2002, Jan, 2), TDMinutes(1))

' an end time
Local endtime:TTime = TTime.Create(TDate.Create(2004, Jan, 1), TDMinutes(4)).addDays(199)

' the period of time between them
Local period:TTimePeriod = TTimePeriod.Create(startTime, endTime)

' the period duration
Local duration:TTimeDuration = period.length()

Print (duration.totalSeconds() / 60) + " minutes"

The answer appears to be 1,336,323 minutes (rounded)

I realise it's not as exciting as working it out yourself from tables... but there's only so much time in a day :-p
