It's a common method in parts of Europe and some other areas to use periods as a thousands separator and commas as the decimal. Here's some of Oracle's documentation on which locales use it:
You'll note that most use a comma for the decimal, and commonly use spaces for the thousands separator. It's really the US and Britain that use the 1,234.5 format.

Good to know, and I wonder why I haven't heard of this before.
However, what I said isn't completely invalid. If you're writing in English, on an English-language website, you should try to write numbers in English too, wouldn't you agree? It's part of the language, and mixing in things that are switched in a different language remains incredibly confusing. Like if someone's native language spelled their word for pig as "horse" and horse as "pig," and they kept referring to pigs as horses despite being on a site with a language where "horse" means horse and "pig" means pig. So even if it's understandable that you might forget, I do still ask that you understand our side of things too and try to remember when you can.
Herbology has multiple greenhouses, so you can concurrently hold classes in more than one greenhouse. If you want to make it less obvious, have the greenhouses space out around the castle and not clumped up in one location, it can even make sense as separate facilities for different plant species could require a minimum distance between those plants.
Also plants that need morning sunlight vs plants that need sunset..
CoMC can be similar with lessons reviewing different creatures in different locations, the weird part for me is that the CoMC classes we saw were all outside, I imagine most other instructors would only be outside for hands on demonstrations with creatures that cannot be brought into a classroom inside the castle, with the remaining time spent in books with rote memorization.
and Bins doesn't need to eat and the rest of the schedule can be worked around him. Alternatively, since ghosts when they die wear the same clothing, he has a ghostly duplicate of a time turner. Nobody tell the unspeakables or dumbledore will have to hire an actual paid history professor.
That doesn't explain why the professors themselves don't know how it works. If it was time turners, that wouldn't be the case. Unless they are lying for the sake of a big, gigantic in-joke at the student body's expense from the entire staff...
Though honestly, assuming one ignores any specific discrepancies, I don't entirely see the issue...
if one assumes that each class meets only once per week for any given student. There's only 7 years, and classes typically take 2/4 houses at a time. Moreover, not all subjects are taught in all years. From the professors' side at least, even the worst subjects only have to teach 2-3 classes a day even with weekends off. Assuming they have ways to save time on the teachers' side of the homework, which is an assumption fair to make with magic involved.
The problem is that big, gigantic "IF" that goes directly against canon for most of everything that's not Astronomy. Therefore, I propose that Hogwarts is fudging the numbers by somehow making one class session count as a session on every day they are scheduled. Possibly in combination with making each class session be Shrodinger's Students, simultaneously every year's students and none of them.
We don't ask about who attends when it's none of them.
EDIT: Alternately, all homework is actually graded by Hogwarts itself, so the professors only ever need to teach the classes. If each class then meets every other day at most, 7 classes a day of 45 minutes or so each isn't undoable.
