So I have someone’s birthdate and the current date. Easy to calculate days old but how to convert that to years taking leap years into consideration. Can’t just divide by 365…
Stupid idea
Substract birthdate (SecondsFrom1970: integer value) to today (SecondsFrom1970: integer value),
Create a brand new date and set the result,
Read the date specs for the # of years, months, days
btw: what are the API2 specs for date ?
http://documentation.xojo.com/api/data_types/datetime.html
There’s even IntervalValue
var interval as DateInterval = currentDate - birthDate
var years as String = "Years: " + interval.Years.ToString
var months as String = "Months: " + interval.Months.ToString
// etc
Not at computer but something like this should do it. Don’t calculate it yourself, that way lies pain and misery.
Perhaps this would this work for you:
Dim birthday As New Xojo.Core.Date(1955, 2, 24, Xojo.Core.TimeZone.Current)
Dim age As Xojo.Core.DateInterval = Xojo.Core.Date.Now - birthday
Try the Beta if you’d like to do this with DateTime.
No need for betas, DateTime is in 2019r2.
The problem is not with DateTime but with DateInterval.
You can’t do this with Xojo 2019r2.1
Var age As DateInterval = DateTime.Now - birthdayand it works with the Beta.
