Ok I have tried to search this forum and other places but to no avail. I'm making a library system for a project at uni and want to log the dates books are borrowed from and until as the number of the day of that year. So 31st Jan 2001 will be 31 and 15 Feb 2001 will be 46 etc. Is there something that will do this for me or am I going to have to bodge something together? I'm not too fussed about rolling into the next year or leap years at the mo.
