Highlight a cell if time for task is over one hour

[Steve M]

Hi
I would like to be able to highlight a cell to show if a start time in
column a and a finish time in column f was over 1 hour. The highlighted cell
could be the finish time cell or a cell next to it. Any help would be great.
Thankyou

Time format I have in cells is hh:mm

cheers

Use conditional formatting with a formula of

=(F2-A2)>=--"01:00"

Brilliant worked a treat thanks.

I also wondered if I could do something similar with another sheet where I
could find out if the start time and finish time where over 12 hours. The
cell format for these dd/mm/yy hh:mm. Start time cell C and Finish time cell
L. Some of the times can run into a few days between start and finish so
need it to work with the date too. Hope that makes sense.

Apologies, the formla works fine for my second question also.
