This is more of a semantics question I think, instead of a translation one, but do you know what does the top left numbering system of magazines like "Weekly Shounen Jump" actually mean? For example:
"２０２５年４月２１日発行４月７日（月）発売第５８券第１７号通券2788号"
I can understand the publishing date and the selling date, but I don't get why they are different? Also the numbering system after that doesn't match the issue which is #19.
From my understanding, there are 2788 Weekly Shounen Jumps ever printed, but the designations 券 and 通券 for numbers 58 and 17 are beyond me. Mainly because in my mind both 券 and 通券 are synonyms of "ticket" most of the times I've encountered them.
