Hi Peter, Christopher, Dennis Thank you all for the suggestions. I tried formulas given by Peter and Christopher. Data and results are as follows. 3:30 is normal SUM, modulo 24. 27.5 is some formula I tried, but it gives minutes as fraction of hour. The Number against 'Peter' is given by Peter's formula and is exactly what I would like. Christopher's formula gives 24.9. Somehow I am unable to open the file attached by Dennis. It gives some error and exits, so I am unable to try it out. 00:30 01:30 00:55 00:50 00:45 01:10 03:50 01:10 05:30 04:25 04:00 02:55 3:30 27.5 27:30 Peter 24:9 Christopher Once again thank you all for the suggestions. For the time being I will go with Peter's formula, but intend to work on the formula given by Christoher and Dennis when I can take some time out.
