सांस्कृतिक नोट्स
Croatians often refer to months by their number (e.g., 'u prvom mjesecu' for January) in casual speech to avoid the complex Slavic names.
In coastal regions, you might hear Italian-influenced names for days or months in very old dialects, though standard Croatian is used in schools.
The concept of 'spajanje blagdana' (joining holidays) means if a holiday is on a Thursday, people often take Friday off to have a long weekend.
Croatian month names are of Proto-Slavic origin, reflecting agricultural and natural cycles.

No, unlike English, days and months are written in lowercase in Croatian unless they start a sentence.
You use the word `sredinom` followed by the Genitive: `sredinom svibnja`.
Croatian uses traditional Slavic names that describe nature (e.g., `listopad` = leaf fall), while English uses Latin names.
Yes, in casual speech people often say `u prvom mjesecu` (in the first month) instead of `u siječnju`.
