Format Date in Spanish

[msteinberger]

Thank you! I ended up with this as my final rule. It displays the date in English or Spanish based on a language column in the data as well as a predetermined date that is also in the data:

function SpanishDate(myDate)
{
var months = ['enero','febrero','marzo','abril','mayo','junio',' julio','agosto','septiembre','octubre','noviembre' ,'diciembre'];
var letterdate = Field("letter date")
var month = months[myDate.getMonth()];
return myDate.getDate() + " de " + month + " " + myDate.getFullYear();
}

return (Field("language") == "S") ? SpanishDate(DateFromString(Field("letter date"))) : FormatDate(DateFromString(Field("letter date")), 'lm d, yyyy');
