My reasoning is that quite a few entries could have the same description, but there would be only a few entries on a day which might reduce the search time a bit.  But then I'm not sure if all entries have a date, which would mess things up.  Anyway, just a thought/suggestion/whatever.)

Btw I wonder if we can do much better than a ~1 minute for ~6000 records. Still I think that with 6000 records the average number of entries with the same description is quite likely to go in the direction of 1. Even if it's a bit higher the algorithm will keep at about O(n) I think, but you may correct me if I'm wrong on that.

It won't hurt and it also contains the progress code which I *like a lot*.
