Unnecessary info: "wan" is the Japanese equivalent of "woof", and "ko" is a suffix meaning little. "wanko" is a cutesy name for dog, but essentially means "little woof"

100% you can do it with some good instructional content and a smidge of patience!
A standard lock is disturbingly easy to pick... We used to run a booth at a maker event where we taught members of the public passing by including, like, 5 year olds to pick padlocks.
Unrelated, but BTW there are some jurisdictions if I'm not mistaken where having lock picking tools found on you is considered "criminal intent" or something, but on the other hand if you're already at the point where your bag is being searched you may already be boned...
Ok, let me rephrase your rephrase to be what question I think you're trying to ask.
At some point we had decided on a seven day week with week names. That's fine. But we must also have decided at some point that today was Wednesday in this system.
So I think you're asking "what is the first day we all agree was definitely a Sunday, such that all Sundays after were based on that". Or put another way, at what point did the days of the week get locked to the days of our year.
I don't have that answer, but your question confused me, so I've reworded it.
Also that's not even a prism, that's a pyramid...
