Hi ! I have a question about the idioms; call it a day/call it a night. After a google search you can understand the general meaning which is to stop doing what you're doing because of tiredness , etc, And about their usage , it says the day version is for things such as finishing working , and night version for finishing leisure activities at night and going to bed. Right?! My question is ; How about people who work night shifts, or finish working not at regular time, Can they say ,let's call it a day, when they finish work at 10 p.m. for example? What if they finish work late, but go out with their friends after ward? call it a day or night?!🙄 I finish work at 9 p m. where I live it's considered night all year round at 9 p.m. if I say let's call it a day when before stop working ,is it natural to your ear? And one more question, some jobs have a fixed ,strict schedule, you finish working at a certain time because you have to, it's not optional, is it natural to use , this idiom in such cases. I'm a teacher, my students know better than me when to start or finish the class, it's not acceptable for them or my boss or even me , to finish the class earlier than usual ,even if we're tired, or we have done enough work, I mean EVERYBODY knows when it's gonna finish , isn't it silly or strange to use the idiom in such cases. I'd appreciate it if you could take time reading my question, and share your experience with me. I agree it's a long question, but Google is our friend but it's not so enough for me😅
