3:15 viisitoista yli kolme = fifteen over three.
3:30 puoli neljä = half four.
3:45 viisitoista vaille neljä = fifteen short of four.
We also use 24 hour clocks but if the dinner is at 17:30, it will just be said to be at half six and you figure am/pm out of context - if it’s ambiguous, we say “six in the morning / six in the evening”.

The convention for (15-minute) fractional hours is to name the fraction of the time from the previous hour to the next one.
eg:
3:15 -> “viertel vier” = “quarter four”
3:30 -> “halb vier” (“hoiba viere” in dialekt) = “half four”
3:45 -> “dreiviertel vier” = “three quarters four”

In English, when they ask the time, we reply: Puolivälissä ohitti apinan perse. Because in English Puolivälissä rhymes with perse.
