How can I change the date format in my template in Partner Tools?

Code example:

This is the EN date:  {%= date("en", "d. MMMM, YYYY", sektion1.whatDate) %} = En: 8. April, 2022

This is the GB date: {%= date("gb", "YYYY MMMM d", sektion1.whatDate) %} = Gb: 2022 April 8

This is the DA date: %= date("da", "YYYY MMMM d", sektion1.whatDate) %} = Da: 2022 april 8 

This is the ES date: {%= date("Es", "YYYY MMMM d", sektion1.whatDate) %} = Es: 2022 abril 8 

This is the HU date: {%= date("Hu", "YYYY MMMM d", sektion1.whatDate) %} = Hu: 2022 április 8
