Language can be precise but also imprecise. When this level of accuracy is intended by the speaker or writer there is no problem. However if the inaccuracy or confusion is not intended there is room for improvement. When it is Saturday and someone tells you he wants to meet you “next Friday” you might be confused. Is this 6 days from now or 13 days. If he meant coming Friday why didn’t he use the much clearer ”coming Friday” in stead of “next Friday”.
The content of a calendar is supposed to be precise. Maybe in Greece you can come hours too late for an appointment, in many other countries this behavior is not accepted.
I find that in the digital calendars I have used (Outlook, Yahoo and Google) there is always an ambiguity when you select a range of dates. I will limit myself here to Google Calendar as I find this product a superior calendar, that I use for many purposes. I give an example of the problem. For instance when you introduce a repeating appointment, you must select the start date and the end date. The end data always has the heading “until”. And I find this until always confusing. Does it include the end date, yes or no? Dictionaries are not clear on this as well. So to the developers at Google: Please replace “until” by “up to and including” or “up to but not including”. I know it is ugly, but clarity comes before looks .
