Is it possible to use Left function in kobocollect

[DJAA]

I want to keep the year from date of birth. for example 2019-03-28 I want to keep only 2019.
Is this possible in kobocollect.

Thank you!

I think you can achieve that by using format-date function.

In the survey tab of your XLSForm:

Data entry screen as seen in Enketo:
