From: Alicia Lopez on 11 Feb 2010 07:40 Hello!! I have a problem. I have a cell array of dates and times and I want to calculate the hours that have been passed between two or more dates. I'm trying to calculate them with the serial date number given by the function datenum. But i only obtain changes in the serial date number when the day changes. Does somebody know how can i get changes in the serial date number when the hour changes??Or does somebody know another way to get what i want?? Thank you very much. Alicia

Just subtract the two datenum values and then multiply by 24. What formula are you using? James Tursa
