Why is it without "sang"?
"Sang" is optional.
But in other sentences it doesn't accept without "sang"...

I guess this question is for the developers.
It's just so confusing
is 'liburan ini ditetapkan oleh ratu' also ok?
Liburan = vacation
Is it really wrong without "hari"?
Why is sang ratu wrong?
A most excellent question.. see the discussion by Femmy813541... it's just extremely annoying there is still no more information
