我将使用什么 Excel function 和过程来计算一列和另一列之间的时间（上午 6 点 55 分/下午 3 点 00 分）？

Question

I need to determine the best way, in Excel, to use the start time in two columns (6:55/AM) and the end time in two columns (1:00/PM) to make 'if'statements such as: If >= 3:00 before 10:00AM, then 'yes'. Can anyone tell me if this is even possible? And what would be the best way for me to start?

I have pulled the 4 columns (6:55/AM/1:00/PM) into two different columns (6:55AM/1:00PM) and then tried using this formula: =text(x16-y16,"hh:mm") but I cannot get it to do anything further. I have searched throughout Stack Overflow and don't see anything that resembles this specific situation.

I need to be able to create if statements such as If >= 3:00 before 10:00AM, then 'yes'. So in the above example, yes would be the response, but if my first columns were to be (7:00/AM) then the response will return no.

Assuming your time values are text (else you would get something very different if you concatenated as you show, I suggest, to convert them to "real" times: (and This will work if the value in C1 is a date/real time or text.)

=C1+IF(D1="AM",0,0.5)

This formula will, in effect, turn the value in C1 into a real time, and add 12 hours to it (1/2 of a day) if the value in D1 is not AM .

NOTE: (provoked by a comment of @K.Dᴀᴠɪs) This formula does no error checking at all, assuming all of your data is how you show in your examples.. If that is necessary, you will need to modify the formula.

Edit To check that something has been entered in C1 , as requested in a comment, just do that. eg:

=IF(C1="","",C1+IF(AND(LEN(C1)>0,D1="AM"),0,0.5))
