Hypnosis can help with your memory, but the question is, is this something you need to remember or is it from a bad event? If the memory is dark, it's possible your mind is trying to protect you from it for now, and when the time is right you can recall.
So my question is, why do you need to remember back to that day and the events before it?
My spatiality is hypnosis, and I am asking these questions to make sure you don't abuse what universe is blocking you from remembering now.
Hope this helps, and if you have any more questions, you can contact me.
All the best.
