Android Question Converting a string

[Sergey_New]

Please tell me how to convert the string "21/01/2020" to "01/21/2020".
I need this to get ticks from a date in "MM.dd.yyyy" format using DateTime.DateParse

Is this for GEDCOM files? Or something similar? Can you post some sample date data?

I wonder how you knew that stuff, GEDCOM!

I had to look it up, and now I know; I also "know" that I don't understand its "great" utility.

Gedcom is not a new Format. It´s base is from 1985 already.
Genealogy by itself is also not new ;-)

I knew this "maybe"

GEDCOM files

If the original data is dates, then is usually better to keep it as dates, rather than needlessly converting it to ticks and back, because sometimes that doesn't work the way you'd expect, eg if the conversion to ticks is encoded on a device with one time zone setting and decoded on another device that has a different time zone setting, or you have date ranges crossing daylight-savings boundaries.

Now you are familiar with the GEDCOM standard
I have attached a working example.
The example sets out my request.
Oops.
Forgot to delete comments. The example works correctly.

Example: today is 24 years since 911 but fall of north tower on 11-Sep-2001 actually happened here on 12-Sep-2001.

Albeit not by much: I remember watching the first tower fall, and then there was a click and the tv went dead which freaked me out a bit, until I realised it was the powerpoint timer that I'd set up to turn the tv off every midnight to deal with my habit of falling asleep in front of the tv.

Thank you! There are probably other exceptions that affect the result. For GedCom purposes, this is not very important.

I created some formatting and conversions of dates and other formats

Dim date2 As String = br.data.data(date1, "dd/MM/yyyy", "MM/dd/yyyy")
Log("date1: " & date1)
Log("date2: " & date2)
