Is this what you want ? difference in year / month or day ?

DateDiff ("yyyy", StartTime, ActualStartTime)

DateDiff ("m", StartTime, ActualStartTime)

DateDiff ("d", StartTime, ActualStartTime)

Thanks but sorry this isn't what I'm looking for.  I want to auto calculate the Actual Start Time form the 'time they arrived' to show how late they are (in minutes).

Where does 'time arrived' come from and what would you use along with it to calculate 'actual start time'?

The Actual Start Time will always be 9am and the arrival time will be entered manually, eg 9.30am, so I just wanted to create a field that auto calculates how late they are eg '30' minutes.

Do you want to use this in your query?

DateDiff ("m", "9:00", ActualStartTime)

Perhaps.

Lateness(m):DateDiff("n", TimeValue("09:00"), [Actual Start Time])

Hi Lilly C,
I provided that solution and Norie just added TimeValue and you ignored my solution. Is this fair?

It is clearly visible that I provided all the inputs even the question was not clear.

Regards,
Pawan

Hi Pawan

I didn't ignore your solution, I copied it into my query and it didn't work, I then copied Nories solution into my query and it did work.

I'm sorry my question was not clear and I don't mean to offend you by not accepting your solution, but on this occasion your solution didn't work for me.

Regards

Lilly

Hi Lilly,
At least you can see that the other expert has change my code a bit. That is quite visible.  Anyways no issues :), Also learn the technique and the logic behind the statement you used. Copy paste will not help down the line.

Bye, Regards,Cheers !!

I didn't copy your code.

After I'd clarified what was required I went away to work on a solution.

I then returned and posted what I came up with.

Unsurprisingly I used DateDiff as you did since that's the standard way to calculate date/time difference in Access.
