is around the clock or round the clock. So either one. So either round the clock

or around the clock. So we use both phrases So let's take a look at the note

here. If someone does something or something happens round the clock

or around the clock it goes on all day and all night

without stopping. So it's literally like you're looking at the clock and it goes

totally around all the hours passed by. So that's why they say around the clock.

Meaning the whole thing without stopping. All right. Let's take a look at some

examples here. Number one. Thomas Edison was known for working around the clock on

his inventions and sometimes did not come home for days. Yeah. If you have ever read anything

about his stories. Basically you know, I think his wife complained that sometimes

he wouldn't come home for 3 or 4 days. He'd be working around the clock. I don't

know, maybe he just took some naps in between. But that was a famous one they

talked about. He used to work around the clock. Or number two. In 1955, Bill Haley and

the Comets, they were ... they had a big hit at that time. They had a big hit called "Rock

Around the Clock. " Yeah. It was a very famous song in the 1950s and then I think later

in the 1970s it was used with the TV show happy days. It was the theme song.

And it went something like you know, one two, three, o'clock four o'clock rock. Five

six, seven, o'clock eight o'clock rock. Nine, ten, eleven o'clock twelve o'clock

rock. You're gonna rock around the clock tonight. That's the way it went. So I

think this song helped to make this phrase even that much more popular. Or

number three here. We could say almost all 711s are open around the clock. We

also say 24/7 a lot to mean you know, the whole day or around the clock ,as

well. And number four here. That factory has three shifts during the busy season.

Those machines are operating around the clock. So they don't have too much time

to stop for maintenance or anything like that. Anyway, I hope you got

it. I hope it was clear. Thank you for your time. Bye-bye.
