Well, it soulds so easy in this case. However, there are other cases, where it
is no so easy.
- -) You have an event that occurs every other monday and wednesday. If you move
the monday event to tuesday, how should the recurrence be updated? To tuesday
and wednesday? Or should both be moved, so the event appears every second
tuesday and thursday.
- -) If you have an event that occurs every two weeks on monday and wednesday,
and you move the monday event to the week before, what shall be the resulting
recurrence?
- -) If you have a montly recurrence, e.g. on the last day of the month, and you
move it to next, should it be changed to recur on every first of the month?
- -) If you have a monthly recurrence on the 25 of each month and you move it to
a 31st, that event won't occur in months with only 30 days... Will the user
be aware of this?
- -) If you have a monthly recurrence on the first tuesday of each month and you
move it one day earlier (to the first monday), you would expect that all
following events are also moved one day earlier, right?
But that's not the case because in months where the first day is a tuesday,
the first monday is six days later and not one day earlier...
So, in short, I have thought about modifying recurrence rules on moving events
quite a lot, but there are so many pitfalls, that I have not yet found a good
way to adapt the recurrence rule in a way that achieves what most users would
probably expect. So I simply decided to not touch the recurrence rule at all.
Cheers,
Reinhold
