The pattern
Use om for a time on the clock, op for a day or a date, and in for a month, a season or a year.
- om + clock time: om acht uur, om twaalf uur. The word uur stays singular. More in telling the time.
- op + day or date: op zaterdag, op 5 mei, op mijn verjaardag. With a day of the week, Dutch often drops op: Ik werk zaterdag usually means this Saturday.
- in + month, season or year: in juni, in de winter, in 2024. Seasons keep their article (the word for "the").
- Parts of the day, with no preposition in front: 's ochtends (in the morning), 's middags (in the afternoon), 's avonds (in the evening), 's nachts (at night). 's morgens means the same as 's ochtends. You will also hear in de ochtend, but the 's forms are the everyday choice.
- van ... tot means from ... until: van negen tot vijf. To include the last day, say tot en met (up to and including): van maandag tot en met vrijdag.

Why it works this way
Think of zooming out on a calendar. A clock time is a tiny point, a day is one square, and a month, season or year is a big block of squares. English does the same with at, on and in, so only one word really changes: at becomes om. A handy picture: om can also mean around (om de hoek, around the corner), and clock hands go round all day. German speakers get a gift: German um, am and im become om, op and in.
You can combine them: op maandag om acht uur, om tien uur 's avonds.
The 's in 's avonds is a fossil, short for des, an old form of the word for "the". Treat the whole thing as one fixed word. At the start of a sentence, the 's stays small and the next word gets the capital: 's Avonds. See when Dutch uses an apostrophe.
Remember: small, medium, large. A clock time gets om, a day gets op, and a month, season or year gets in.
