Hola ʻehia kēia? = What time is it?
Hapalua hola ʻehiku o ke ahiahi = Seven-thirty in the evening
I typed "seven thirty oʻclock in the evening" and was marked incorrect.
"Seven thirty in the evening" also does not work.
It must be :7:30 in the evening" or "7:30 pm."
I tend to use numbers, but noticed above that RonRGB hyphenated seven-thirty. That might be the thing, as that suggests time, not just 2 numbers. Hmmm.
