Each year we run a camp. Each year I produce the 24-page handbook using OPro on RISC OS. 90% of the content is the same as the previous year, with the dates adjusted. Each year I forget to update at least one of the dates. Is there a way to set up these dates so that they are calculated using offsets from one date field, and displayed as dates? For example the equipment loading might be D-1, the departure day D, thefirst day in camp D+1, to use a system more common among the military. D+1 would then be shown as Monday 24th July this year, then Monday 23rd July next year, because the origin date will be changed. I appreciate it's easy in a spreadsheet, and I could therefore mailmerge them in, but I wondered whether there was an applet for example which could do this?
