Autogenerating Age in Years and months from Date of Birth

[Collins McAdoyo]

Hi Team members, I was creating a survey with Variables Date of Birth and Age. Is it possible to autogenarate Age in Years and Months from the date of birth entered?

 

.......

Q3. Enter date of birth (dd/mm/yyyy): ______/_______/__________

 

....

 

Q5. Current Age: Years:________________ Months:____________

 

 

Thanks

This is Dynamite!

Steven, we're always very impressed by your work, I wonder if you might like to post something about the use and methods of the Calculate function?

Hello Neil
Will do so... I am currently working on a tool that is taking your KOBO to the greatest test limits so I will be able to document a lot based on this assignment with calculate function among other functions that I found could work with the sytem. So probably at a later stage. Thanks for the complement. On a lighter note since last year we are now implementing national level Study Number 11 using KOBO (teams have nicknamed the phones KOBO and call each other Koblets)

Fantastic! Do please let us know more about your study, I'll add something to the user showcases for you. We often call eachother "KoBoNauts"
