"Tomorrow is Sunday."

Translation: ʻO ka Lāpule ka lā ʻapōpō.

[YABQ8Odp]

why is the word for Sunday before the word for tomorrow?
In the previous question the word for Saturday came
after the word for yesterday

[Hawaiian-German]

Both are right

[RonRGB]

(1. ʻekahi) Monday = ka Pōʻakahi

(2. ʻelua) Tuesday = ka Pōʻalua

(3. ʻekolu) Wednesday = ka Pōʻakolu

(4. ʻehā) Thursday = ka Pōʻahā

(5. ʻelima) Friday = ka Pōʻalima

(6. ʻeono) Saturday = ka Pōʻaono

Sunday = ka Lāpule

Which day? = Ka pōʻahia?

[rabelon]

Po'ahia is "day of the week."
Ka lā 'ehia is "which date."

[Keniko1]

Why 'o?

[GaryBisaga]

It’s defining “tomorrow” as equivalent to “Sunday.” Hence the ʻo equational sentence type.
