Words Capitalized in English, but Lowercase in Croatian

Months

English: January, February, March, April, May, June, July, August, September, October, November, December

Hrvatski: siječanj, veljača, ožujak, travanj, svibanj, lipanj, srpanj, kolovoz, rujan, listopad, studeni, prosinac

Days of the Week:

English: Monday, Tuesday, Wednesday, Thursday, Friday, Saturday, Sunday

Hrvatski: ponedjeljak, utorak, srijeda, četvrtak, petak, subota, nedjelja

Titles of Books, Movies, Songs, etc.

English uses title case (capitalizing the first letter of each major word) in the titles of books, movies, songs, and other works.

English: The Lord of the Rings

Croatian generally capitalizes only the first word and any proper nouns in the title.

Hrvatski: Gospodar prstenova

Adjectives derived from proper nouns

Generally, adjectives formed from proper nouns are capitalized in English (e.g., American, Croatian) but not in Croatian (e.g., američki, hrvatski).

Hrvatska (with a capital H) is the name of the country. A"hrvatska" (lowercase h) is used when it functions as an adjective, such as in "hrvatska obala" (Croatian coast).

Personal pronoun 'I'

The Croatian first-person singular pronoun "ja" ("I") is always written in lowercase.

In summary, the most common and important difference to remember is that Croatian does NOT capitalize months and days of the week. Everything else is mostly the same as in English, with some nuances in titles of works, derived adjectives, and 'I'.
