Hi Jo,
Sorry i can't help with that alignment, but it wouldn't surprise me if there's an app or website calculator where you might find the answer.
BTW welcome to the forum.
Best

EDIT: I searched on "planetary alignment calculator" and this was one of the results - Maybe this, just keep watching speed it up and watch the years go by... (no moon shown though
) and switch to overhead view....
