What is correct usage of 'while'? Is it correct to use 'while' here?

Please consider the day and timing while/when you expect me to respond on call.

  • 'While' is not correct here. It might be more usual to say, Please choose (decide on) a day and a time you would like me to call. Dec 5, 2020 at 13:50
  • Please could you explain why cant we use while here?

  • We use while when speaking of something that happens at the same time that something else is going on. "The telephone rang while I was in the bathroom." - "Please wait while I fasten my shoe." Dec 5, 2020 at 18:01

"While", when used as a conjunction, means during.

If you use 'while' in your example, that would mean that you are asking the person to consider the day and timing at the same time they expect you to respond. I don't believe that is what you are trying to say.

I think you are trying to say that, when waiting for you to respond to a call, they should consider the day and time, because that will have a bearing on how quickly you respond.
