"Di mana Anda hari Rabu?"

Translation: Where are you on Wednesday?

[glhaynes90]

In colloquial English, "on" is also not required. "Where are/were you Wednesday?" is an acceptable translation.

[ChrisPwise]

Rarely. More to do perhaps american english as this course is.
'On' would be used even in street english.

Could it not also be "Where were you on Wednesday"? Or is this never interpreted in the past tense?

This sentence could be past/present tense.
It depends on the context.
Since there is no context here, both English translations (are/were) should be acceptable.

Could it also be "where will you be on Wednesday" or "where are you on Wednesdays (in general)"?
