Welcome to the Make community!
You’ll have to translate the date before you can use the date format tokens, which only supports English.
So you’ll have to do something like this,
{{replace(replace(replace(replace(replace(replace(replace(replace(replace(replace(replace(replace(1.time; "január"; "January"); "február"; "February"); "március"; "March"); "április"; "April"); "május"; "May"); "június"; "June"); "július"; "July"); "augusztus"; "August"); "szeptember"; "September"); "október"; "October"); "november"; "November"); "december"; "December")}}
(copy-paste the above into the field, or type it exactly as shown)
For more information, see related thread:
Hope this helps! Let me know if there are any further questions or issues. P.S.: investing some effort into the tutorials in the Make Academy will save you lots of time and frustration using Make!
