View calendar in other languages

Hi,

I am designing a questionnaire in spanish and I have a date variable to record respondents age of birth. However, when viewing the question in Tester, the calendar interface to fill the question is displayed in english. Is it possible for it to display in other languages, such as spanish?

In case it is not clear, I mean the calendar interface that you see in the image below.

thanks in advance

The calendar is part of the functionality provided by the OS. Hence, switch your OS language to Spanish.
