RSS Events in Chronological Order
Over the past few years, we keep hearing from people trying to paste RSS feeds into XML parsers that they want to get events back in chronological order.So, we've answered your desire, but please, please, PLEASE be aware that if you use this parameter, what you get from our feed will frequently NOT WORK IN RSS READERS for very, very, very clear reasons. I can explain why again, but I hope everyone here is aware of them and just wants the events to be sorted for uses other than feed readers.
In other words, this is an unsupported parameter, and if you write to us asking for help getting it to work in your feed reader, there likely won't be anything we can do about it for you.
If you would like to make the XML give you events that would normally appear in ascending start date order, then you can pass along ?sort=start-date-asc to the normal RSS URL. Then you can parse the XML as if it were a chronological list of events. They will disappear from your feed whenever their start date is in the past.
If you want more flexibility than that, you should really be using the API (http://upcoming.yahoo.com/services/api/), as you should not mistake RSS for a flexible XML API, because it's not. =P Now that i've given you fair warning, feel free to proceed...

If you get the original default feed and resort it, there's no guarantee that those are in fact the next 25 upcoming events. Get it?
This kind of stuff is very tricky, so don't worry if you run into problems when trying to use anyone's (not only ours) RSS feeds that contain events inside. There are actually two relevant date/time points per event *at the least*, and RSS as a format only can handle one at a time.
you are wrong. bluesmoon is correct. tested and confirmed with pipes.
