Yes, that is exactly the mistake that GP is elucidating.

GP?

GP = Grandparent / reference to the poster of the comment 2 levels above

Yes, but it was unclear to me until I worked through it because op didn’t make it as obvious as it could have been. I figured if I was confused others might be too, so I typed it out explicitly.

I did kept thinking too. Thanks for pointing it out.

The original problem being that it should have been 2024 - 42.

Yeah you're right - I re-structured my post before hitting on "reply" and mangled what was originally something like this:

2024 - 942 = 1082 instead of 1982.

(I also removed a detailed description of how these errors are usually caused by a mistype by those who do not use a keyboard with a number pad and by poor handwriting making 0 and 9 look similar.. but I cut that out as otherwise we're be here all day reading my rambling thoughts).

or a bizarre Y2K problem

Maybe 2024 - 1942?
