This is a rare case in which both languages actually use word order the same way to indicate something.
"Yesterday was Saturday." answers the question "What day was yesterday?" "Saturday was yesterday." answers the question "When was Saturday?"
You could override the effects of the word order with sentence intonation and not sound like a loon, but I suspect that is not what you had in mind.
It works the same in Czech.
In my opinion, it would be a missed teaching opportunity to accept your answer.
