Month Translation in Field and in Calendar

Hi!

I am experiencing an issue with the translation of months in the field.

**Generally a correct Greek translation** of months in a WordPress format (j F Y, l) is displayed as seen below with the equivalent pickadate format (d mmmm yyyy, dddd):

4 Απριλίου 2019, Πέμπτη < This spelling of month April is correct for the field.

The months in the calendar should have a different spelling as seen below:

Απρίλιος 2019

Can the **field** display the translated Greek month April as 'Απριλίου' and the **calendar** display a different spelling of the translated Greek month as 'Απρίλιος'?

This is the correct grammer in Greek.

Thank you
