I noticed that I and Alexa say “six ‘oh’ five a m”, but is that the correct way of saying the time? Specifically the “oh” part?

Kind of like when speaking out a phone number, how we might say “my number is one two three, six ‘oh’ six…” but really, that’s not an “oh” like the letter O even though it looks like an O, but everyone knows the person is saying “six zero six”, which is the proper way of saying that.

Edit: thanks for all the answers everyone! This was just pure curiosity for me but I really enjoyed reading everyone’s responses and learning some new things!

        I don’t actually know the reasoning behind it. We have a rather small company and in 2003 we outsourced our accounting to a nationwide firm that does accounting for a lot of huge worldwide franchises. Our work weeks went from Monday to Sunday, but this accounting firm said that all their clients had Thursday to Wednesday weeks, so we had to change to that system. We’ve since taken our accounting system back inhouse, but we’ve kept the Thursday through Wednesday weeks.

        I had never heard of that weekly system before 2003, but now I’ve realized that it’s quite popular. I think it’s more of a system used in franchise type companies rather than manufacturing or other type businesses.
