This is just a suggestion for the suggestion box; it occurred to me as I was adding some events to the calendar today (courtesy of
Linux Magazine, which includes a list of upcoming events in each issue).
I think it might be helpful to adjust the date routine so that, when someone changes the start month, the end month updates to the new month. Updating the day of the month field could be helpful too, but I personally find having to change the month field more irritating than having to enter a new numerical date.
Just a thought.
