Convert number to date

Hi all,

What is the simplest way to do the following conversion:

2019091 = 01/03/2019
2019121 = 01/04/2019
2019152 = 01/05/2019

The pattern of the above is that the first 4 numbers = YYYY and the last 3 = Total days past in YYYY.
I want to convert the first number string/number to a date with the format DD/MM/YYYY.



Try this:

Str = "2019091"

Int32 year = Cint(Str.substring(0,3))

Int32 days = Cint(Str.substring(4,Str.Length))

requiredDate = new DateTime(year, 1, 1 ).AddDays(days).ToString(“dd/MM/yyyy”)


Thank you very much!

I’ll try it right away and return with a status soon :slight_smile:

hello @lakshman

I tried this code and it works good and properly accoding to the condition you have specified but as you can see @LarsFeilberg wants something like this

He wants date of a month back
So @LarsFeilberg use this code

If you have created the workflow as suggested by @lakshman than just make minor changes
Inplace of 2019 input the year variable and in place of 91 add Days Variable


Hi again,

For some reason i get an error when trying to create a substring using str.length as the length parameter.

I’m defining days as = Cint(str.Substring(4,str.Length))

Can you explain to me why is is?

I have done the following work around:

days = Cint(right(str,3))

With this work around and with @vickydas requiredDate value it works like a charm.

Thanks you very much for the help both @vickydas & @Iakshman :slight_smile:
