Months, and why they're never capitalized
Ten minutes on the topic's other two pieces: the twelve months, all masculine and all international names, take a fixed -у ending after у with no exceptions - у јануару, у септембру - and neither days nor months are ever capitalized in Serbian, not even at the start of a sentence. Build sentences about a schedule and some rest before choosing and translating your way through the rest.

Months
The twelve months: јануар, фебруар, март, април, мај, јун, јул, август, септембар, октобар, новембар, децембар - all masculine, and all international/Latinate names.
To say in a month, use у + a special -у ending: у јануару, у марту, у септембру. This ending belongs to the locative case (covered fully in a later lesson) - for now, just learn у + [месец]у as one fixed chunk.
Special cases
Недеља means both Sunday and week - context tells them apart. A less common synonym, седмица, exists specifically for week.
The one exception is positional, not lexical: a day or month name is capitalized only when it happens to start a sentence, exactly like any other word - never in a date or a title.
