Croatia uses the day-month-year date notation and both the 24-hour and the 12-hour clock for expressing time of day.
The month can be spelled out in lower case (e.g. 17. ožujka 2018. for 17 March 2018) or represented by an Arabic or Roman ordinal number (17.
[dan] ožujka "the 17th [day] of March"), but the nominative case (e.g. 17. ožujak 2018.)
[3][2] Leading zeroes in dates should be omitted in non-technical situations, and the names of months and days of week are only capitalised at the beginning of a sentence.
However, instead of the English "a.m."/"p.m." system, descriptive phrases are used in cases of ambiguity, e.g. ujutro "in the morning", prijepodne "before noon", poslijepodne "afternoon", navečer "in the evening".
